00:00:02,820 --> 00:00:07,950
Good afternoon. Just before I introduce for speaker, I welcome you all here.

2
00:00:07,950 --> 00:00:16,740
Can you note that this talk is being filmed and livestreamed, including the questions and answers?

3
00:00:16,740 --> 00:00:23,040
Welcome to the Oxford Martin School. Thanks for joining us here this afternoon for a lecture by Dr. William Bird.

4
00:00:23,040 --> 00:00:29,280
This is a joint lecture between the Oxford Martin School and the Rockefeller Foundation Economic Council on Planetary Health,

5
00:00:29,280 --> 00:00:35,490
which is a mouthful for those who don't know us. The Economic Council on Planche Health launched in 2017.

6
00:00:35,490 --> 00:00:42,600
It's based here at. The Oxford Martin School, is tasked with making the economic and policy case for planetary health with communicating

7
00:00:42,600 --> 00:00:46,650
the links between human health and the natural systems on which they depend.

8
00:00:46,650 --> 00:00:54,170
Our report will be published next year, so keep an eye on our website Planetary Health Dot Dot Dot UK or our Twitter feed.

9
00:00:54,170 --> 00:00:57,990
Ox Planet Health for more details.

10
00:00:57,990 --> 00:01:05,580
More importantly, tonight, the lecture will be followed by a drinks reception next door in the cafe, so please do join us afterwards.

11
00:01:05,580 --> 00:01:08,910
After the talk will be having a 20 minute questions and answers session.

12
00:01:08,910 --> 00:01:16,470
So if you want to leave your questions to the end, that would be fantastic to introduce your speaker, Dr William Bird.

13
00:01:16,470 --> 00:01:22,350
We're glad to have you here today and B he's the CEO and founder of Intelligent Health.

14
00:01:22,350 --> 00:01:31,220
He's a practising doctor who started to get his patients more active by setting up the first Health Walk scheme in 1996.

15
00:01:31,220 --> 00:01:36,260
This led to him creating the green GM a year later as he realised that companionship and

16
00:01:36,260 --> 00:01:41,060
contact with nature were major driving forces in keeping people active and healthy.

17
00:01:41,060 --> 00:01:47,630
You also helped to set up a health forecasting unit at the Met Office, where clinical director for five years,

18
00:01:47,630 --> 00:01:53,540
providing forecasts to help keep health professionals predict and plan for weather related illnesses.

19
00:01:53,540 --> 00:01:58,930
He's an adviser to the World Health Organisation, Public Health England and Sport England.

20
00:01:58,930 --> 00:02:04,340
They set up Intelligent Health eight years ago. With that, companies created the innovative innovative.

21
00:02:04,340 --> 00:02:11,360
Beat the Street and a physical activity intervention programme adopted by cities all over the UK.

22
00:02:11,360 --> 00:02:17,360
Beat the Street has had more than nine hundred and fifty thousand participants to date and has helped to create sustained behaviour change,

23
00:02:17,360 --> 00:02:22,520
making healthier and more active communities. And I'm sure we'll hear more about this later today.

24
00:02:22,520 --> 00:02:34,990
Williams going to talk to us about why we need a fourth revolution in health care.

25
00:02:34,990 --> 00:02:35,920
Thank you very much, sir.

26
00:02:35,920 --> 00:02:44,410
And it is a real pleasure to be here, and it's great to have the inter-disciplinary of where you have everyone in a very different kind of sphere.

27
00:02:44,410 --> 00:02:48,370
When I worked at Natural England, I remember being next to the dormouse specialist.

28
00:02:48,370 --> 00:02:53,110
So everything you need to know about Dormouse was in the man sitting next to me.

29
00:02:53,110 --> 00:02:58,210
And he knew everything about dormice, and I just thought, here I am as a doctor sitting next to a dormouse specialist.

30
00:02:58,210 --> 00:03:01,720
That's brilliant because I'm sure something eventually will connect.

31
00:03:01,720 --> 00:03:09,180
We never did, but it was one of those things, and it started because I was brought up with my father being a doctor.

32
00:03:09,180 --> 00:03:11,350
And when I first started in life,

33
00:03:11,350 --> 00:03:17,380
I was actually born above the surgery and my mother was a naturalist and we used to have stuffed birds in the fridge.

34
00:03:17,380 --> 00:03:25,480
So it was a household where medicine and nature were connected all the way through, and I probably carried on ever since.

35
00:03:25,480 --> 00:03:34,000
So what I want to talk about and I'm borrowing from great people here who have been thinking about this, but in my way,

36
00:03:34,000 --> 00:03:41,350
I've been trying to do the practical side of thinking about how do we actually deliver health care to be sustainable for the future?

37
00:03:41,350 --> 00:03:45,780
And. Let's start with the revolution.

38
00:03:45,780 --> 00:03:52,080
So the first revolution to public health was very much the one we know from the 19th century.

39
00:03:52,080 --> 00:03:55,200
It started with clean water, the sewage being sorted out,

40
00:03:55,200 --> 00:04:02,550
housing being sorted out and air quality first started to be addressed and workplaces were starting to become healthier.

41
00:04:02,550 --> 00:04:10,470
So huge advances in health from that public health, and that's continued all the way through.

42
00:04:10,470 --> 00:04:16,330
However, we still have some of the worst housing in Europe. The damp housing, the coldest housing.

43
00:04:16,330 --> 00:04:22,230
So still some way to go. So a great revolution, one revolution to modern medicine.

44
00:04:22,230 --> 00:04:32,220
So that's the medicine I've been delivering, delivering as a GP for many years antibiotics, surgery, physiotherapy,

45
00:04:32,220 --> 00:04:41,850
all the things that we are completely used to over diagnostics and again, massive inroads on treating cancers that we never thought could be treated.

46
00:04:41,850 --> 00:04:48,420
Hodgkin's lymphoma is now almost 100 percent curable, whereas before it used to be almost 100 percent fatal.

47
00:04:48,420 --> 00:04:57,090
HIV now is almost completely curable or at least contained, and modern medicine has done an incredible amount of good.

48
00:04:57,090 --> 00:05:06,120
So great on that. We're entering and kind of started the third revolution, which is out of personal health,

49
00:05:06,120 --> 00:05:12,760
but we're now actually more in control of our health with internet of actual knowledge.

50
00:05:12,760 --> 00:05:17,700
Wearables that tell us a huge amount about our steps and about our heart rate and

51
00:05:17,700 --> 00:05:22,410
about our fitness and all sorts of apps and other things that we can actually do.

52
00:05:22,410 --> 00:05:27,150
And then you can have your genomes checked to find out what your genetic makeup is.

53
00:05:27,150 --> 00:05:33,210
So you know exactly the ace inhibitor is going to be right for you, but not right for the person next door.

54
00:05:33,210 --> 00:05:39,180
So we start to do this. Precision medicine Precision medicine is where, with your genomics,

55
00:05:39,180 --> 00:05:47,340
we know what would be best for that person with those genes or that lifestyle or that behaviour change.

56
00:05:47,340 --> 00:05:56,910
And actually, that's just remember that precision medicine isn't just genomics and and drugs, it is actually about understanding someone's behaviour.

57
00:05:56,910 --> 00:06:03,030
So you target messages directly to that person. Great.

58
00:06:03,030 --> 00:06:14,120
So that's it sorted. But we can look forward to more disease because what's happening is that our life expectancy increases.

59
00:06:14,120 --> 00:06:22,880
You can see on the right you've got men and women and on a right hand side, he gains in years of multimorbidity.

60
00:06:22,880 --> 00:06:31,940
So over five years for men and about five years for women, but life expectancy is only going to go up to three and a half years or three years.

61
00:06:31,940 --> 00:06:45,410
So you've got those extra two years on average of disease, of living with multimorbidity of two, three, four or even five long term conditions.

62
00:06:45,410 --> 00:06:50,420
And that's going to get worse as we go into the next 20 years.

63
00:06:50,420 --> 00:06:59,150
So although modern medicine is great at saving our lives, the things like Alzheimer's, the things like diabetes,

64
00:06:59,150 --> 00:07:06,290
cardiovascular disease, where there's damage to the heart with heart failure, we're not actually managing to completely cure it.

65
00:07:06,290 --> 00:07:12,440
Well, holding it and we're holding it very well. People don't die, but they don't get completely cured as well.

66
00:07:12,440 --> 00:07:14,690
So this is one factor.

67
00:07:14,690 --> 00:07:24,890
We've got long term conditions and we've got also with all of this, we've got antibiotic resistance that's going to be developing.

68
00:07:24,890 --> 00:07:28,190
Long term conditions will continue.

69
00:07:28,190 --> 00:07:41,270
So another four million people will be having arthritis in 2035, another 1.6 million people will have diabetes in 2035, compared to what we got now.

70
00:07:41,270 --> 00:07:47,870
So as life expectancy goes up, we obviously going to get more diseases, which are an ageing.

71
00:07:47,870 --> 00:07:55,140
So we're living now with more long term conditions and with people with more disability.

72
00:07:55,140 --> 00:08:01,200
So you can say, is that a success? Is that something which is good?

73
00:08:01,200 --> 00:08:11,160
What about health inequalities, they'll be doing well on that. Well, but not so the gap between those who are healthy and for life expectancy of males

74
00:08:11,160 --> 00:08:17,460
and life expectancy in females has remained remarkably stubborn all the way through,

75
00:08:17,460 --> 00:08:22,950
and billions and billions have been spent on trying to narrow that gap of health inequalities.

76
00:08:22,950 --> 00:08:31,320
And as you can see here up to 2016, we're not doing a very good job.

77
00:08:31,320 --> 00:08:40,080
We're indoors, but disconnected from nature. We started to get disconnected from each other, creating isolation and loneliness.

78
00:08:40,080 --> 00:08:47,090
And with all that heat coming out there, we've got some global warming as we actually look in our own houses.

79
00:08:47,090 --> 00:08:55,230
Inactivity because of cars means you've got more pollution and you get more carbon use and global warming again.

80
00:08:55,230 --> 00:09:04,930
The urban heat islands, as we have less vegetation to be able to deal with urban heat, lack of trees and therefore lack of trees.

81
00:09:04,930 --> 00:09:12,610
It all fits with global warming again. So we can see here there are certain conditions and are certain aspects of both human

82
00:09:12,610 --> 00:09:20,950
health and global health that go hand in hand and inflammatory diet deforestation.

83
00:09:20,950 --> 00:09:31,600
And again, global warming. So we know quite clearly the sustainable lifestyle, a lifestyle where we actually having an anti-inflammatory lifestyle.

84
00:09:31,600 --> 00:09:40,510
Talk about that in a minute actually fits in perfectly with the prevention of global warming.

85
00:09:40,510 --> 00:09:50,230
And we can see here, of course, we don't need any introduction to the global warming side there, so we're left despite these three great revolutions,

86
00:09:50,230 --> 00:09:59,110
we're left with long term conditions that are here to stay and we'll get more and more prevalent as we get long, live longer.

87
00:09:59,110 --> 00:10:07,270
We've got health inequalities that hasn't budged and we've got global warming and not one of those three revolutions.

88
00:10:07,270 --> 00:10:14,710
Unfortunately, save the public health if we can get that right is able to has many managed to bulge this.

89
00:10:14,710 --> 00:10:20,530
In fact, some people feel the actual personalised health care is going to widen health

90
00:10:20,530 --> 00:10:24,310
inequalities because those in the know who've got more knowledge have got

91
00:10:24,310 --> 00:10:28,840
more ability to make a difference will actually find they're going to be better

92
00:10:28,840 --> 00:10:37,300
using that personalised health and health inequalities will get better. So let's go back to find out where it's all gone wrong.

93
00:10:37,300 --> 00:10:43,090
Let's find out how we can address those three big problems that we've got.

94
00:10:43,090 --> 00:10:48,580
So if we go back to being a HUNTER-GATHERER about 100000, 200000 years,

95
00:10:48,580 --> 00:10:52,450
I probably get all sorts of anthropologists here over time exactly how far we go back.

96
00:10:52,450 --> 00:10:58,180
But it's probably about one 100 or 200, and we put a thousand years for one hour.

97
00:10:58,180 --> 00:11:01,600
So that's about 100 hours. That's about four days.

98
00:11:01,600 --> 00:11:09,430
And you can see here that we were hunter-gatherers, and everything in our existence was a brilliant Hunter-Gatherer engine,

99
00:11:09,430 --> 00:11:13,600
and nothing really much changed until we came to about 10 hours ago.

100
00:11:13,600 --> 00:11:21,490
And that's when agriculture came. So it was still outdoors. We were still very good as a outdoors, but we weren't wandering around anymore.

101
00:11:21,490 --> 00:11:24,640
As hunter-gatherers, we were still in those groups.

102
00:11:24,640 --> 00:11:30,940
But all of that time, we have been getting better and better and better as being a hunter gatherer four hours ago,

103
00:11:30,940 --> 00:11:36,450
civilisations in Mesopotamia and in Egypt.

104
00:11:36,450 --> 00:11:44,520
And then big changes for nine minutes to nine minutes ago was the industrial revolution, so that's when the call came along.

105
00:11:44,520 --> 00:11:52,790
So. If you talk to your grandpa or your great grandfather, you could still probably save it in the 1950s and 1960s,

106
00:11:52,790 --> 00:12:02,200
they were still active, still outdoors, are still roaming around the streets. So despite this inactivity creeping in,

107
00:12:02,200 --> 00:12:10,840
there was still a lot of activity in the 50s and 60s as the industrial revolution had well developed and the cars were very much there.

108
00:12:10,840 --> 00:12:15,310
So when did the change come? Well, it's actually a few seconds ago.

109
00:12:15,310 --> 00:12:21,310
So just 80 seconds ago, it was technology and indoor culture.

110
00:12:21,310 --> 00:12:27,420
So I've got a wonderful story of a family in Sheffield and ED.

111
00:12:27,420 --> 00:12:33,000
Who's eight years old and his great grandfather both lived in the same area still.

112
00:12:33,000 --> 00:12:45,360
I have always done for four generations. The great grandfather in 1919 was able to wander six miles with his friends, go out in the morning,

113
00:12:45,360 --> 00:12:53,010
come back when it's dark, as it as all instruction for these eight year olds going out wandering six miles.

114
00:12:53,010 --> 00:12:58,620
Can you imagine now letting your eight year old go out and thin come back when it's dark?

115
00:12:58,620 --> 00:13:03,690
But that was it what it was like in 1919 in the 1950s when Ed's grandfather was out.

116
00:13:03,690 --> 00:13:08,340
He could go about a mile. But in that mile there were woods.

117
00:13:08,340 --> 00:13:16,590
Those valleys. There was an old mine they used to go to. And again, it was go out in the 50s, come back when it's dark.

118
00:13:16,590 --> 00:13:22,110
Then its mother in the 70s, well, she could go to a swimming pool, which is half a mile away,

119
00:13:22,110 --> 00:13:26,640
but come back in an hour, come back in two hours because I want to know where you are.

120
00:13:26,640 --> 00:13:32,540
So we just started to get that feeling that things were right and.

121
00:13:32,540 --> 00:13:37,820
He can't go out. So he is locked. He can go to the parents.

122
00:13:37,820 --> 00:13:42,560
But no way. Eight years old is allowed out of the house. So something's happened.

123
00:13:42,560 --> 00:13:47,840
Something fairly catastrophic has happened in society for us to have this fear

124
00:13:47,840 --> 00:13:52,820
and this anxiety that we cannot let our children can say all sorts of things.

125
00:13:52,820 --> 00:14:00,500
Traffic was obviously completely different than newspapers were different about what the news and the internet and everything else was like.

126
00:14:00,500 --> 00:14:07,820
But basically, now human beings are locked mostly indoors for a lot of the time.

127
00:14:07,820 --> 00:14:12,710
But if we look at our factory settings of what we should be like as a hunter gatherer.

128
00:14:12,710 --> 00:14:18,890
But it's very simple. It's three things people, we should be all connected together place.

129
00:14:18,890 --> 00:14:22,580
We're connected to nature. We're connected to a supportive environment.

130
00:14:22,580 --> 00:14:26,420
And the environment is vibrant and we have purpose.

131
00:14:26,420 --> 00:14:34,010
We've got value. We get up in the morning and we know what we should be doing and who we are and why we're here.

132
00:14:34,010 --> 00:14:41,540
That's pretty much it. And if you do the five ways to wellbeing or understand those that are put on the bottom of connecting to each other,

133
00:14:41,540 --> 00:14:52,850
taking notice of things around you and then being active, giving and keep learning, that's how factory settings, that's where we should be.

134
00:14:52,850 --> 00:14:59,900
This is where we're beginning to go in this last 80 seconds, loneliness.

135
00:14:59,900 --> 00:15:06,560
So we know that loneliness is equivalent for cardiovascular disease, smoking 20 cigarettes a day.

136
00:15:06,560 --> 00:15:13,130
So loneliness is a highly stressful thing. It's not isolation because some people love to be isolated.

137
00:15:13,130 --> 00:15:17,450
We actually think of nothing better than to go out and be completely on your own.

138
00:15:17,450 --> 00:15:22,280
So loneliness is a perception that you're feeling excluded so you can be lonely in the workplace.

139
00:15:22,280 --> 00:15:26,150
You can be lonely, the family, you can be lonely in the school.

140
00:15:26,150 --> 00:15:32,090
The hostile environments we've created, parts of Oxford are absolutely wonderful to walk around.

141
00:15:32,090 --> 00:15:38,030
Parts of Oxford are not good to walk around, and some places are absolutely intimidating.

142
00:15:38,030 --> 00:15:44,150
And that disconnection to nature and lack of control, lack of purpose in our lives.

143
00:15:44,150 --> 00:15:49,740
And because that's so far away from where we've been. That creates a fear.

144
00:15:49,740 --> 00:15:55,770
And chronic stress, because our bodies were designed for this. And said we've got this.

145
00:15:55,770 --> 00:16:04,230
So the human mismatch hypothesis that Lee had started to think about and is now obviously for

146
00:16:04,230 --> 00:16:10,920
many of you will know about it is basically say this is our ideal environment in this circle.

147
00:16:10,920 --> 00:16:21,090
But unfortunately, our new environment has shifted, which means you've got an area of mismatch, an area our bodies are not designed for.

148
00:16:21,090 --> 00:16:32,630
Bay Area and people feel insecure where all our cells and everything that we've done in our life doesn't feel it's quite connected together.

149
00:16:32,630 --> 00:16:41,090
So this fear, chronic stress illness that then leads on to changes in our lifestyle.

150
00:16:41,090 --> 00:16:49,480
So first of all, inactivity. But we'd actually do this, let's do this one first to diet and obesity.

151
00:16:49,480 --> 00:16:57,090
So when you're chronically stressed. And we're talking about chronic stress, acute stress, that's a very different thing, and that's quite normal.

152
00:16:57,090 --> 00:17:04,390
You actually stop eating and you lose weight. You take up all your carbohydrates to cope with this situation.

153
00:17:04,390 --> 00:17:07,440
When you're chronically stressed, you release ghrelin,

154
00:17:07,440 --> 00:17:13,350
which comes from the stomach and it goes up to the brain and goes up to receptors all around the body.

155
00:17:13,350 --> 00:17:19,590
And it's designed to cope with your chronic stress because things are bad, you gentlemen.

156
00:17:19,590 --> 00:17:26,340
The next meal is coming. You don't know if it's going to be a famine or something in the body, saying there's stress, therefore must be a problem.

157
00:17:26,340 --> 00:17:36,510
So the gradient comes up and cortisol, of course, increases your calorie intake and that increases, particularly in mice.

158
00:17:36,510 --> 00:17:41,370
But also, they have done in humans carbohydrate preferring to fat.

159
00:17:41,370 --> 00:17:51,270
So you actually crave the carbohydrates and actually, as you take sucrose of carbohydrates and sugars, the anxiety is allayed.

160
00:17:51,270 --> 00:17:56,070
So you get this wonderful feedback that when you're stressed Greenland is making,

161
00:17:56,070 --> 00:18:03,480
you want to eat more carbohydrates and put on more calories and you get rewarded in your dopamine for actually having it.

162
00:18:03,480 --> 00:18:10,860
So no wonder this comfort eating gets so good when you're stressed, you can feel how you're needing to have this carbohydrate.

163
00:18:10,860 --> 00:18:16,140
But of course, there's no point in having all that carbohydrate is all going to be expended and disappear.

164
00:18:16,140 --> 00:18:18,720
You've got to store it. So where do you store it?

165
00:18:18,720 --> 00:18:25,800
You store in a place that doesn't get in the way of running and doesn't get in the way of throwing a spear in the abdomen.

166
00:18:25,800 --> 00:18:27,540
So that's where visceral fat,

167
00:18:27,540 --> 00:18:38,430
the visceral fat is the storage of the extra load of calories that you've taken because Greenland is saying store as much energy as you possibly can.

168
00:18:38,430 --> 00:18:44,970
We don't know what's going to happen next, and visceral fat is very different from subcutaneous fat.

169
00:18:44,970 --> 00:18:52,460
Actually, we don't care about subcutaneous fat. It's actually not very harmful the visceral fat in your stomach.

170
00:18:52,460 --> 00:19:00,470
That is harmful for cells, just get bigger because it's only a temporary measure in subcutaneous fat,

171
00:19:00,470 --> 00:19:05,780
you get more fat cells in visceral fat, they just get bigger. So you get lots of bigger, bigger,

172
00:19:05,780 --> 00:19:14,420
bigger cells of adipose tissue and those adipose cells get too big so they don't get enough nutrients and oxygen in the middle,

173
00:19:14,420 --> 00:19:18,980
and therefore it creates an inflammatory reaction because they become hypoxic.

174
00:19:18,980 --> 00:19:27,590
And as you get these large cells, you start to get unsustainable and visceral fat is an incredible source of inflammation.

175
00:19:27,590 --> 00:19:31,820
So it's not a great thing to have. It's only meant to be dead temporarily.

176
00:19:31,820 --> 00:19:38,450
When you become stressed, you also become inactive again, possibly because you're just trying to conserve energy.

177
00:19:38,450 --> 00:19:44,210
But your motivation drops and you find you can't go to the gym and you can't do the runs.

178
00:19:44,210 --> 00:19:50,450
You can't even go for the walk anymore. When you're chronically stressed, physical inactivity is encouraged.

179
00:19:50,450 --> 00:19:57,310
So what is chronic stress that's come in and fear releases stress hormones?

180
00:19:57,310 --> 00:20:04,750
Also, smoking, drinking alcohol, why is that because you're inhibitory fibres are diminished and your inhibitory fibres,

181
00:20:04,750 --> 00:20:08,330
obviously, if you're about to be, have a line jump at you.

182
00:20:08,330 --> 00:20:12,280
You don't get a spreadsheet and talk about a cost benefit analysis of which way you're going to go.

183
00:20:12,280 --> 00:20:15,820
You jump. Whichever way you're going to go, you leap.

184
00:20:15,820 --> 00:20:25,960
So your brain takes away the inhibitory, which means that smoking drinking alcohol can start to become much more of an issue when you're under stress.

185
00:20:25,960 --> 00:20:33,190
So you think of places where there's chronic stress. It's not surprising that we've got these behaviour changes and then that leads

186
00:20:33,190 --> 00:20:37,780
on to something else because the immune system gets in the in the game now.

187
00:20:37,780 --> 00:20:45,010
So you think if you are going to be in a family, we're going to be in a war or you're going to be attacked by animals?

188
00:20:45,010 --> 00:20:48,280
You've got to make sure your immune system is raised up.

189
00:20:48,280 --> 00:20:55,960
So chronic inflammation is one of the consequences of the chronic stress, and that's going to be a big thing I want to talk about.

190
00:20:55,960 --> 00:21:01,600
It's a chronic inflammation is when the immune system rises above its baseline and starts purring away.

191
00:21:01,600 --> 00:21:08,410
Think of your computer when it's trying to do some background stuff, a viral check or whatever it is.

192
00:21:08,410 --> 00:21:19,330
You Typekit you type something into the computer. Nothing changes because it's doing some background when your immune system is raised up.

193
00:21:19,330 --> 00:21:23,380
It takes all the energy from every other part of the body. It's king.

194
00:21:23,380 --> 00:21:27,550
The immune system takes more energy from anything else. It takes it away from the brain.

195
00:21:27,550 --> 00:21:33,070
So the brain actually is unable to do complication things and think differently.

196
00:21:33,070 --> 00:21:40,030
So when you've got this chronic inflammation, your brain starts to diminish. You get tired, you can't concentrate so much.

197
00:21:40,030 --> 00:21:45,770
But the big thing about chronic inflammation is unfortunately.

198
00:21:45,770 --> 00:21:52,820
It is the source of all of those diseases or supportive of those diseases, if not the cause.

199
00:21:52,820 --> 00:22:00,950
Cardiovascular disease is probably the first one. Cardiovascular disease is entirely an inflammatory condition.

200
00:22:00,950 --> 00:22:07,010
You've got your little fatty streaks on the artery and they create inflammation.

201
00:22:07,010 --> 00:22:10,520
Macrophages pass through immune system. Start to come to it.

202
00:22:10,520 --> 00:22:19,820
Increasingly, you get more and more inflammation until eventually it ruptures, and all the therapeutic stuff comes out and you get a clot.

203
00:22:19,820 --> 00:22:24,050
So all through the immune system or through the cardiovascular system, you've got inflammation.

204
00:22:24,050 --> 00:22:30,110
And if you measure just CERP, it would be raised. It's an inflammatory disease.

205
00:22:30,110 --> 00:22:36,230
And now we start to look at diabetes as an inflammatory disease and cancers as inflammatory diseases,

206
00:22:36,230 --> 00:22:41,570
even anxiety and depression are now thought to be inflammation of the brain.

207
00:22:41,570 --> 00:22:48,230
You create inflammation of the brain and anxiety will come through. Arthritis, of course, is inflammatory.

208
00:22:48,230 --> 00:22:56,150
So our bodies, when our immune system is purring away and going up and up, seem to respond in a particularly bad way.

209
00:22:56,150 --> 00:23:02,990
Originally, it was to help us to survive, but unfortunately that's no longer.

210
00:23:02,990 --> 00:23:12,260
So we have a new problem problems, chronic stress and inflammation, and these are the conditions you find in the more deprived communities.

211
00:23:12,260 --> 00:23:16,940
So it's not surprising that health inequalities hasn't shifted if we don't get

212
00:23:16,940 --> 00:23:22,310
to the root problem of dealing with chronic stress and chronic inflammation.

213
00:23:22,310 --> 00:23:29,630
CSI. OK, so that's how you can remember chronic stress, chronic inflammation.

214
00:23:29,630 --> 00:23:35,870
So we've got three conditions here. Long term conditions, health inequalities, global warming, which haven't been sorted out.

215
00:23:35,870 --> 00:23:40,250
We now know about the reason and some of it.

216
00:23:40,250 --> 00:23:44,000
So let's have a look at the fourth revolution. We'll call it total health.

217
00:23:44,000 --> 00:23:54,680
You can call it one health. You can call it planetary health. We can call it a way which identifies where you have the person, the individual health.

218
00:23:54,680 --> 00:23:58,280
But instead of being in modern medicine where that is isolated,

219
00:23:58,280 --> 00:24:06,610
that has to be totally connected to health of a place where they live and totally connected to the health of the community.

220
00:24:06,610 --> 00:24:15,040
Out of a three come together as one and is slightly more than public health, which is behaviour change,

221
00:24:15,040 --> 00:24:22,030
although obviously green space is now which is part of public health is a bit of social prescribing is lots of things.

222
00:24:22,030 --> 00:24:28,450
But what we have to do is make sure there's three central parts all connected together.

223
00:24:28,450 --> 00:24:36,970
Hypocrisy is, of course, as always, gets always gets all the glory because he felt environmental causes and natural treatments of

224
00:24:36,970 --> 00:24:42,910
diseases and the need for harmony between the individual and the social and the natural environment.

225
00:24:42,910 --> 00:24:48,490
How about that? Absolutely. Spot on. And we've kind of forgotten about the nature.

226
00:24:48,490 --> 00:24:54,270
We've kind of forgotten about the natural environment around us.

227
00:24:54,270 --> 00:25:01,950
They've even probably forgotten about the community aspect of health as I've been sitting in my GP practise doling out antibiotics when needed.

228
00:25:01,950 --> 00:25:09,180
I have to show is I do that only when I need it. But also things thinking about the person thinking about their social setup.

229
00:25:09,180 --> 00:25:16,140
But I wouldn't be thinking so much about the parks around, but now I do, and this is where we have to to go.

230
00:25:16,140 --> 00:25:20,610
So let's have a look at the person. Oh, I forgot to mention my sponsor feature.

231
00:25:20,610 --> 00:25:25,260
So if you can look at all of those major effects on a faulty immune system,

232
00:25:25,260 --> 00:25:30,960
reducing pro-inflammatory markers increases antioxidants reduces oxidative stress from Krebs cycle.

233
00:25:30,960 --> 00:25:36,690
That means it's extraordinary in the fact that each mitochondria gets stronger and prolongs the life of cells.

234
00:25:36,690 --> 00:25:44,130
Frankly, stimulation to Belarus over telomeres get longer, which we talk about reduces blood pressure, visceral fat, obesity, hypertension.

235
00:25:44,130 --> 00:25:47,280
I've got about 15 tablets to do that, and this is just one tablet.

236
00:25:47,280 --> 00:25:55,500
And, of course, the stimulation of brain derived neurotrophic factor, which helps to prevent dementia and Parkinson's.

237
00:25:55,500 --> 00:26:01,590
So if you want shares in it, it's free.

238
00:26:01,590 --> 00:26:08,060
That's Fitch rates going for a walk.

239
00:26:08,060 --> 00:26:13,070
Going for a walk sounds really dull. It sounds really nice.

240
00:26:13,070 --> 00:26:18,470
And when I tell a patient to go for a walk, they can say, my granny could tell me that you're meant to be a qualified doctor,

241
00:26:18,470 --> 00:26:22,610
give me those tablets, send me to the hospital and I want to see the top specialists.

242
00:26:22,610 --> 00:26:30,000
I don't want this to be told to go for a walk. OK, well, let's have a look see what all can do.

243
00:26:30,000 --> 00:26:35,740
Major fault immune system. That is what the datasheet of a dream drug would be.

244
00:26:35,740 --> 00:26:43,600
And we got to get really excited by that. We would be so excited if one drug did all of those things, it would just sort out the world.

245
00:26:43,600 --> 00:26:48,070
And yet, because it's wrapped up in a walk is kind of lost interest.

246
00:26:48,070 --> 00:26:57,370
And yet it outcome is identical to about 15 polypharmacy, drugs and an older person to be taking to get that exact result.

247
00:26:57,370 --> 00:27:02,680
And you want to tell me why that's four times strength, that particular walk.

248
00:27:02,680 --> 00:27:07,900
What's going on there? What else is going on? I that sunshine.

249
00:27:07,900 --> 00:27:13,120
Yes, thank you. So how many times we're being told to wrap up completely and not ever go in the sun?

250
00:27:13,120 --> 00:27:18,100
And now suddenly we get rickets? We think, Oh, actually, the vitamin D is quite important.

251
00:27:18,100 --> 00:27:24,800
So yes, we don't get burnt, we don't get calluses. But sunshine is important.

252
00:27:24,800 --> 00:27:31,610
Social to people, loneliness, similar to 20 cigarettes a day for cardiovascular disease companionship,

253
00:27:31,610 --> 00:27:36,350
we are designed to be but depends who the companion, of course, is.

254
00:27:36,350 --> 00:27:42,580
Some companions you might not want to go with, but companionship is important and the last one is.

255
00:27:42,580 --> 00:27:51,880
Greenspace, yeah. So I can promote a book, The Oxford Textbook of Nature and Public Health at £42, which we mean helping to edit.

256
00:27:51,880 --> 00:27:59,920
So it brings all the evidence about green space, which is extraordinary now about how it improves and impacts the brain health.

257
00:27:59,920 --> 00:28:06,820
So here we have four times the strength of a drug of the dream, and it's a walk.

258
00:28:06,820 --> 00:28:10,660
That's all it is. That is where health should be.

259
00:28:10,660 --> 00:28:19,660
That's how we should be doing it. Let's have a look a little bit more about the walking and the inflammatory response, how it helps the inflammation.

260
00:28:19,660 --> 00:28:26,410
We know the inflammation. That's a cause of many of these chronic diseases. Let's go back to this bit.

261
00:28:26,410 --> 00:28:30,790
That's not actually visceral fat. That's visceral fat.

262
00:28:30,790 --> 00:28:38,350
The stuff inside the white you can see inside the halo around the outside is subcutaneous fat.

263
00:28:38,350 --> 00:28:44,770
You may not like that subcutaneous fat. Actually, I didn't mind it too much. I really, really mind you having that visceral fat in the middle.

264
00:28:44,770 --> 00:28:49,870
And what's so unfair about this one is that between the two top and the bottom,

265
00:28:49,870 --> 00:28:57,730
one's got 4.3 litres of visceral fat and the other one's got 4.5 litres of visceral fat and you've got the same waist circumference.

266
00:28:57,730 --> 00:29:06,820
How unfair is that? Voice circumference is a good proxy measure of visceral fat, but as you can see here, it's not perfect at all.

267
00:29:06,820 --> 00:29:14,040
And I should explain why visceral fat so such a problem because of the inflammatory response it gives.

268
00:29:14,040 --> 00:29:19,410
Bring back the Fisher Rex Patrick's sorts of visceral fat, just like that.

269
00:29:19,410 --> 00:29:26,670
You can see the orange there is the amount of visceral fat is reduced just by walking for 13 weeks.

270
00:29:26,670 --> 00:29:38,040
The subcutaneous fat is the dark blue, and the more you have in diabetes, the more the visceral fat, which is one of the big components of diabetes.

271
00:29:38,040 --> 00:29:43,930
It disappears, so you can imagine a patient. Obese patients didn't lose any weight, either.

272
00:29:43,930 --> 00:29:52,240
So he did all that walking. And for this study, that's a little bit more in order to not lose weight, but still a visceral fat plummeted.

273
00:29:52,240 --> 00:30:02,290
So they are much healthier now. Are they going to tell me that no way they're going to come back and said, Stop that walking is an absolute nonsense.

274
00:30:02,290 --> 00:30:07,810
Still can't get my genes on. I still can't get myself together. I'm still way exactly the same as I did.

275
00:30:07,810 --> 00:30:13,570
It's nonsense. I only go for diets with physical activity, as I said, Well, look inside you look inside you.

276
00:30:13,570 --> 00:30:19,390
That visceral fats disappeared. Well, we haven't got a CT scanner in the surgery, so we can't do that.

277
00:30:19,390 --> 00:30:25,240
But that's where physical activity specifically can attack that part.

278
00:30:25,240 --> 00:30:29,590
Let's have a look at the other things you can do. Just get walking. Contract your muscles.

279
00:30:29,590 --> 00:30:32,620
You get your kinds of kinds of interleukins.

280
00:30:32,620 --> 00:30:39,520
And then you get an anti-inflammatory bath in every part of your organ for a few hours after every exercise you do.

281
00:30:39,520 --> 00:30:48,700
So it calms down immune system, just as it's meant to do, because obviously when you're exercising, everything's good and all fine and dandy.

282
00:30:48,700 --> 00:30:54,870
And then let's get back into the nitty gritty of the cells. So here's a cell.

283
00:30:54,870 --> 00:31:01,360
Sure, you've heard of the mitochondria. And whenever the mitochondria came from.

284
00:31:01,360 --> 00:31:12,650
Yeah, thank you very much. About a billion years ago, as life was working itself out, a little bacteria fused with another bacteria and life began to,

285
00:31:12,650 --> 00:31:17,740
you carry it, life began and we've kept those mitochondria as little bacteria ever since.

286
00:31:17,740 --> 00:31:25,450
And they don't need power. Everything that we have. But they also power trees and slugs and snails are not actually very special people.

287
00:31:25,450 --> 00:31:31,630
We just use exactly the same batteries as pretty much the whole of life.

288
00:31:31,630 --> 00:31:37,060
So let's have a look inside that mitochondria. You've got antioxidants.

289
00:31:37,060 --> 00:31:41,860
You've got its own DNA and you've got results for oxidative phosphorylation.

290
00:31:41,860 --> 00:31:46,030
Here's a sedentary, high calorie, probably high rather than high fat and stress.

291
00:31:46,030 --> 00:31:54,230
So this is a bad place to be. Battery charges up every battery has to charge up.

292
00:31:54,230 --> 00:32:01,660
OK, so your batteries are all charged up now because you been sitting. OK.

293
00:32:01,660 --> 00:32:09,580
You're not moving very much. So what is about to happen in your bodies and billions and billions of little cells,

294
00:32:09,580 --> 00:32:14,140
is you going to start to leak out free radicals because of all that heavy lunch?

295
00:32:14,140 --> 00:32:20,620
You had a bit of a stress you've got because cortisol makes it worse and you're not moving

296
00:32:20,620 --> 00:32:25,170
around means you start getting free radicals because it can't hold that charge anymore.

297
00:32:25,170 --> 00:32:29,560
The outer membrane of mitochondria is absolutely at full capacity.

298
00:32:29,560 --> 00:32:34,330
And it just can't hold it. So just like overcharging your mobile phone, it gets warm.

299
00:32:34,330 --> 00:32:40,930
The battery gets warm. That's electrons leaking out, also known as free radicals in the human body.

300
00:32:40,930 --> 00:32:49,060
So these free, free radicals, the leaking out, not because we're energised, moving around because we're sitting down doing nothing.

301
00:32:49,060 --> 00:32:54,880
And the antioxidants aren't able to cope because they haven't been stimulated enough.

302
00:32:54,880 --> 00:33:03,640
So get moving, start to walk around, start to be active, perhaps have less calories on board and reduce stress.

303
00:33:03,640 --> 00:33:12,670
And now the mitochondria purrs way. Of mitochondrial health in Cambridge, he says it's like a dynamo.

304
00:33:12,670 --> 00:33:20,500
It just needs to be moving all the time. You've got to keep your mitochondria going the whole time and then free radicals

305
00:33:20,500 --> 00:33:25,420
fade away because the pressure would destroy the potential difference as reduced.

306
00:33:25,420 --> 00:33:30,760
Antioxidants lift up, more mitochondria come through, cleans out all the debris in the cell.

307
00:33:30,760 --> 00:33:39,060
The cell becomes much happier. Healthier. Well, let's have a look and see why those free radicals ended up.

308
00:33:39,060 --> 00:33:47,360
Because they didn't just stay in the mitochondria, those free radicals of oxidative stress ones come out.

309
00:33:47,360 --> 00:33:52,220
And they hit the chromosome again to the nucleus.

310
00:33:52,220 --> 00:33:58,460
So what sort is telomere business? Okay. Well, the telomeres were discovered or the purpose of them?

311
00:33:58,460 --> 00:34:00,980
Elizabeth Blackwell at University of California,

312
00:34:00,980 --> 00:34:10,040
for which she got the Nobel prise and she got the Nobel prise because people knew the end of every chromosome as a repetitive genomic structure,

313
00:34:10,040 --> 00:34:13,520
which meant nothing and it didn't programme any genes or proteins at all.

314
00:34:13,520 --> 00:34:17,090
It was just sitting there and nobody quite knew what it was.

315
00:34:17,090 --> 00:34:24,230
And then she realised that telomeres at the end, as she called them for longer than people did better.

316
00:34:24,230 --> 00:34:31,200
They had less disease and they were healthier and actually following some of the people through, they got less diseases.

317
00:34:31,200 --> 00:34:38,760
And it's like a cap like a shoelace at the end of a but little plastic bits at the end of a shoe laces stop that chromosome unravelling,

318
00:34:38,760 --> 00:34:42,270
but also stopping chromosomes joining together.

319
00:34:42,270 --> 00:34:54,900
But its big thing is every time a cell divides, the telomere gets a bit shorter until it gets so short that cell can no longer divide.

320
00:34:54,900 --> 00:34:59,100
And when that cell can no longer divide, it doesn't get replaced.

321
00:34:59,100 --> 00:35:04,820
And when that cell doesn't get replaced. You will want to sell short.

322
00:35:04,820 --> 00:35:15,110
Which could be a bit of your brain, a bit of your muscle, but if your bone all shrinking and that tipping point is 28 years old,

323
00:35:15,110 --> 00:35:20,900
so everyone piles to it, I'm afraid are sliding down, I've been sliding down for a long time.

324
00:35:20,900 --> 00:35:26,810
And but if you've got very long telomeres, that 28 year old actually can be longer.

325
00:35:26,810 --> 00:35:35,600
And if you've got very short, telomeres get shorter. And what we know now when we think about the fourth revolution of health care is not

326
00:35:35,600 --> 00:35:41,600
only the physical activity actually helping protect us from those free radicals.

327
00:35:41,600 --> 00:35:49,580
But if you're a child and it's had a very difficult upbringing, the adverse childhood events, then you'll cramp.

328
00:35:49,580 --> 00:35:54,410
Your telomeres will start off shortly before you've even started your adult life.

329
00:35:54,410 --> 00:35:57,860
So the chances of living in a very deprived area,

330
00:35:57,860 --> 00:36:07,640
having had a very difficult childhood with lots of perhaps abuse or nutritional problems or stress as a child,

331
00:36:07,640 --> 00:36:16,210
the chance of you living longer is going to be very small because those telomeres are already short, so.

332
00:36:16,210 --> 00:36:20,040
We've got this whole light course to actually think about.

333
00:36:20,040 --> 00:36:27,870
But there's only one thing that releases something called Tumblr and Tumblr rays can make those telomeres go longer again,

334
00:36:27,870 --> 00:36:34,860
and that's physical activity. I can assure you there are lots of laboratories in the world trying to work out, how do we make Tumblr res?

335
00:36:34,860 --> 00:36:40,230
Because you can imagine if you took two batteries and it hit those telomeres and made them grow longer.

336
00:36:40,230 --> 00:36:45,090
Hey, presto, you've got a picture of life and nowhere near nowhere near.

337
00:36:45,090 --> 00:36:54,390
It's probably been more complicated, but walking a simple thing we just talked about can do that.

338
00:36:54,390 --> 00:36:58,410
That cell, when he can't divide anymore, goes into the licence,

339
00:36:58,410 --> 00:37:10,650
sends out massive explosion like a supernova of inflammatory markers so that the immune system can destroy it and apoptosis, it disappears.

340
00:37:10,650 --> 00:37:15,480
So every time cells get to the end of their life, they're creating more and more inflammation.

341
00:37:15,480 --> 00:37:21,810
Which is why as you get older and older, inflammatory markers go up a little bit.

342
00:37:21,810 --> 00:37:29,100
OK, let's have a look and see what are settings are for health, for green space.

343
00:37:29,100 --> 00:37:34,230
So we said it's people place and purpose the place bets.

344
00:37:34,230 --> 00:37:38,970
Here's some pictures of a pretty horrible outlook.

345
00:37:38,970 --> 00:37:50,540
I think this is in South Korea, but these students were divided into four groups and one lot saw these pictures and loads of others.

346
00:37:50,540 --> 00:37:57,200
A lot, a lot of students, so of CGI thrown in some trees, exactly the same pictures as above,

347
00:37:57,200 --> 00:38:01,850
but with trees and green space and flowers and other things on it.

348
00:38:01,850 --> 00:38:10,940
Another group has exactly the same bottom, but the green trees were just a little bit microsecond released.

349
00:38:10,940 --> 00:38:15,570
Subliminal. So they weren't aware in the cortex that it was happening,

350
00:38:15,570 --> 00:38:20,880
but subliminally they had the trees released and the fourth group had the trees

351
00:38:20,880 --> 00:38:24,330
explained to them by someone sitting next to them as they were looking on the screen.

352
00:38:24,330 --> 00:38:30,690
So all of these were done on screens. They did some complicated, backward digital Dhubri thinking, I can't remember,

353
00:38:30,690 --> 00:38:35,460
but you have to subtract 13 from a big number and keep subtracting 13 until you make a mistake.

354
00:38:35,460 --> 00:38:38,580
Probably the most stressful thing you could possibly imagine.

355
00:38:38,580 --> 00:38:45,270
And then they did the experiment, and then they did exactly the same experiment on those four groups.

356
00:38:45,270 --> 00:38:53,220
So what happened? How's our brain wired? Does it really make a difference if you look at a screen with those?

357
00:38:53,220 --> 00:38:59,150
Or should we have to be outside in nature and should things make any difference at all?

358
00:38:59,150 --> 00:39:05,420
Well, the first one, those who looked to grey urban landscapes with no greenery at all.

359
00:39:05,420 --> 00:39:06,920
They did worse.

360
00:39:06,920 --> 00:39:18,050
And every study that's been done has shown exactly the same thing after mean looking green or grey infrastructure with no water and no trees,

361
00:39:18,050 --> 00:39:23,780
we actually get stressed and therefore our brain gets less effective.

362
00:39:23,780 --> 00:39:31,370
The two who looked at trees both subliminally and in real birds in exactly the same,

363
00:39:31,370 --> 00:39:35,720
which indicates that this is deep in our brain, is deep in our limbic system.

364
00:39:35,720 --> 00:39:39,830
This is our reptilian brain and where a lot of this is happening.

365
00:39:39,830 --> 00:39:44,210
And then the other group has someone next to them, of course, did very well because we like to have a social.

366
00:39:44,210 --> 00:39:54,720
We like to learn. We like to feel there was something about it. So if that is so good, they can start to reduce stress.

367
00:39:54,720 --> 00:40:03,560
And depression and surely the inequalities will get better because it will reach those people who are.

368
00:40:03,560 --> 00:40:04,970
Most needy.

369
00:40:04,970 --> 00:40:16,340
So if you can look here is a study done quite a long time ago by Popcom and Rich Mitchell, so you can see here the lowest income is the dark blue.

370
00:40:16,340 --> 00:40:24,860
The middle income and the middle one and the highest income is the light blue. On the left is the ratio of death and case of death.

371
00:40:24,860 --> 00:40:30,770
The higher that is, the more death is happening.

372
00:40:30,770 --> 00:40:38,240
So the first thing you can see is if you look at each of those segments, the inequalities is horrendous.

373
00:40:38,240 --> 00:40:46,170
Those in the very poor areas are dying much as how much greater rate than those who are affluent.

374
00:40:46,170 --> 00:40:54,710
But as you go across the green spectrum, but the little hiccup at the beginning bit towards the end, there is a very green environment around them.

375
00:40:54,710 --> 00:41:06,280
That gap has really shrunk. And that's because the green space and the greenery and nature is a way of making our brains feel comforted.

376
00:41:06,280 --> 00:41:09,730
It feels that we're not under pressure anymore. There's no famine to being.

377
00:41:09,730 --> 00:41:16,300
We can see trees. Therefore there must be life. There must be water, there must be shade, there must be animals, there must be food.

378
00:41:16,300 --> 00:41:27,670
So the more we see water biodiversity, the friendliness not to, you know, not too thick undergrowth, we actually start to feel better and our brain.

379
00:41:27,670 --> 00:41:33,190
And you can see here the gap between the rich and the poor is diminished hugely.

380
00:41:33,190 --> 00:41:42,720
Well, an incredible thing to be able to do just by being able to change the landscape of a city.

381
00:41:42,720 --> 00:41:45,820
So we've mentioned about loneliness.

382
00:41:45,820 --> 00:41:55,270
And I think we can probably all experience that part of stress where you've got a sleep disturbance, engage in less physical activity,

383
00:41:55,270 --> 00:42:04,410
increase pain, depression, fatigue, poor health is all the things that happen when you're stressed or when you're lonely.

384
00:42:04,410 --> 00:42:08,520
And inflammation count goes up, inflammation count also goes up,

385
00:42:08,520 --> 00:42:17,580
and telomeres get shorter in carers and carers who are looking after patients of Alzheimer's have a spouse

386
00:42:17,580 --> 00:42:24,210
of Alzheimer's or a child of severe autism have some of the highest stress levels that we can measure.

387
00:42:24,210 --> 00:42:28,800
They've got the equivalent of soldiers coming back from Afghanistan.

388
00:42:28,800 --> 00:42:37,200
And when a patient when their spouse dies after three months, all inflammatory markers go down again.

389
00:42:37,200 --> 00:42:42,090
So we've got this stress built into society in all sorts of ways.

390
00:42:42,090 --> 00:42:52,620
The loneliness, the carers, those who feel left out, those who feel in a in a difficult relationships are whole aspects and children in particular.

391
00:42:52,620 --> 00:42:56,670
So let's have a look and see what we've got in the people.

392
00:42:56,670 --> 00:43:01,800
So we got this people purpose place chronic stress and poor health behaviours, mitochondrial damage,

393
00:43:01,800 --> 00:43:06,540
telomere shortening, chronic inflammation and that creates our long term conditions.

394
00:43:06,540 --> 00:43:10,960
That's my world. But actually, it's more than that.

395
00:43:10,960 --> 00:43:19,450
Because if you look at this. Chronic stress and inactivity, poor concentration, tiredness, irritability, addiction,

396
00:43:19,450 --> 00:43:26,650
depression, weakness, chronic inflammation of all consequences of this mismatch.

397
00:43:26,650 --> 00:43:29,680
And as a society, you get less people out of doors.

398
00:43:29,680 --> 00:43:36,280
Therefore, the streets become less safe because there's less vigilance, poor air quality because people are in their cars, reduced learning in school.

399
00:43:36,280 --> 00:43:40,380
Because children do worse, they're stressed or they've got no inactive,

400
00:43:40,380 --> 00:43:46,210
very inactive productivity at work goes down because people are inactive or eating the wrong things,

401
00:43:46,210 --> 00:43:51,310
and therefore the brain is being devoured of energy dependence of elderly because people who

402
00:43:51,310 --> 00:43:56,800
haven't been active for their lives therefore are more prone to false sarcopenia and other things,

403
00:43:56,800 --> 00:44:01,120
less volunteering because they're less people outdoors, less people connected to each other.

404
00:44:01,120 --> 00:44:14,290
Isolation. Obesity. This activity was walking, this very simple thing starts to completely, if it's not there, destroy society.

405
00:44:14,290 --> 00:44:18,210
An inactive. Community is a dying community.

406
00:44:18,210 --> 00:44:21,120
It can't function as it should be.

407
00:44:21,120 --> 00:44:28,440
There's no interaction, there's no interaction with the place, there's no interaction with people, get it right and everything points.

408
00:44:28,440 --> 00:44:31,800
Everything spirals upwards and feeds on itself.

409
00:44:31,800 --> 00:44:36,150
Because the more people are out in the park, the more people want to go in the park because it feels safe,

410
00:44:36,150 --> 00:44:39,450
the more people talking to each other, the more people want to go out to talk to each other.

411
00:44:39,450 --> 00:44:52,920
Because it becomes the norm, it becomes a cultural norm. So our focus in health has kind of gone from let's build tennis courts, swimming pools.

412
00:44:52,920 --> 00:44:59,250
And football pitches. That's how I used to when I was in the 1990s. That's what I was told as a doctor.

413
00:44:59,250 --> 00:45:03,170
That's how you get patients active. And I saw my diabetic patients.

414
00:45:03,170 --> 00:45:07,740
They said, I hate sport, I hate swimming pools. I can't bear the gym.

415
00:45:07,740 --> 00:45:16,210
I was tough. You can't do anything. And then of course, I went for a walk with my dog.

416
00:45:16,210 --> 00:45:20,730
I went past all the houses, the GP and everyone where they all live.

417
00:45:20,730 --> 00:45:25,020
And I was a single patient out walking on a lovely July evening.

418
00:45:25,020 --> 00:45:32,910
And I thought, Hang on a sec, you tell me you can't do all these fancy things like gym and go swimming and all of that, but you go for a walk.

419
00:45:32,910 --> 00:45:36,360
And actually, that's how the health folks I see because we realise the men,

420
00:45:36,360 --> 00:45:41,580
the men were worried they wouldn't be able to get back because they were about to climb every style bit.

421
00:45:41,580 --> 00:45:46,620
And they worried about getting lost. And the women are worried about fear of being alone.

422
00:45:46,620 --> 00:45:50,370
So hence we got the walking groups together. But this is how we were meant to be.

423
00:45:50,370 --> 00:45:55,080
And this is the exercise referral decommissioned by Nice because it had no evidence.

424
00:45:55,080 --> 00:45:59,250
But after 12 weeks, it made the job a difference to your physical activity.

425
00:45:59,250 --> 00:46:02,820
So now it's been asked not to commission it.

426
00:46:02,820 --> 00:46:10,020
It can work in a few isolated places, but they've got it right. Then we went to the community based services.

427
00:46:10,020 --> 00:46:17,100
The park runs, the health, walks, green gyms, the salsa classes, all of those things which we can see in a community thriving,

428
00:46:17,100 --> 00:46:27,000
brilliant, fantastic, got people all in groups, and that's where we start to democratise physical activity.

429
00:46:27,000 --> 00:46:35,670
And that's what we're doing now, which is social prescribing. Social prescribing is where people can actually lead a walk or go for salsa or do

430
00:46:35,670 --> 00:46:40,920
art therapy or do dance or do whatever it is to be able to get people engaged.

431
00:46:40,920 --> 00:46:47,650
But we're not going into our fourth revolution like that. That's still where we are now.

432
00:46:47,650 --> 00:46:54,660
The fourth revolution. Actually relies on the entire community taking ownership.

433
00:46:54,660 --> 00:47:00,720
Everyone becomes a fitness instructor, the doctor for his patients, the teacher first for the pupils,

434
00:47:00,720 --> 00:47:09,140
the shopkeeper for their customers, the workplace manager for the employees.

435
00:47:09,140 --> 00:47:18,710
Receptionists, everybody starts to take control of the health and those around us, and we start to share it together.

436
00:47:18,710 --> 00:47:27,060
And that's a social movement. So that is a social movement where we start to own the problem of health,

437
00:47:27,060 --> 00:47:32,730
and that's where walking and all these other things connexion to nature arts,

438
00:47:32,730 --> 00:47:40,020
and all of those things start to help to narrow the gap between health inequalities, to help the climate change.

439
00:47:40,020 --> 00:47:47,940
Because we know that obviously is going to be everything we do. There is going to be helpful for that and long term conditions can be allayed.

440
00:47:47,940 --> 00:47:52,890
We shouldn't have diabetes, we shouldn't have as existing.

441
00:47:52,890 --> 00:48:03,510
A few people might be able to get it, but everyone was active. And if everyone ate a very normal, reasonable diet, we wouldn't have diabetes.

442
00:48:03,510 --> 00:48:09,480
Not near. We have it now. It is a disease that could almost be obliterated.

443
00:48:09,480 --> 00:48:15,330
Just imagine having no diabetes in a community because everyone has taken on the health themselves,

444
00:48:15,330 --> 00:48:22,090
working with each other and using what's around them as medicine.

445
00:48:22,090 --> 00:48:31,680
The fisheries medicine they're taking. So let's have a look and just see how it can work, how you can motivate if this is a green gym.

446
00:48:31,680 --> 00:48:40,230
So that's conservation work. Here's a lady who's been doing the green gym and she went to aerobics as well, and we monitor her heart.

447
00:48:40,230 --> 00:48:44,670
And we looked at her and said, OK, you've been doing step aerobics. What did you do?

448
00:48:44,670 --> 00:48:48,540
Well, 20, 10 minutes, 15 minutes. We did the warm ups and everything like that.

449
00:48:48,540 --> 00:48:53,430
And then we did the real hard workout, got my abs sorted out, my pecs and everything like that,

450
00:48:53,430 --> 00:48:58,950
and I got my heart rate up to here and I was training out of breath and marine breathing rate went to this and it was really exciting.

451
00:48:58,950 --> 00:49:02,740
Remember just to calm down and we did 20 minutes. Really hard work as a brain.

452
00:49:02,740 --> 00:49:09,780
That's fantastic. All about herself and her body, which is OK, but she had a good time.

453
00:49:09,780 --> 00:49:12,030
She loved it. She went and she had some people.

454
00:49:12,030 --> 00:49:20,470
She then went to the green gym and you can see that is a tool to tell you how to work out an X in a post or at the beginning.

455
00:49:20,470 --> 00:49:29,100
Then the heart rate goes up if you notice that heart rate goes up more than 20 minutes more than an hour.

456
00:49:29,100 --> 00:49:34,080
In fact, it went on for two and a half hours in the cardiovascular training zone.

457
00:49:34,080 --> 00:49:42,330
So she was doing conservation work for two and a half solid hours at a training level.

458
00:49:42,330 --> 00:49:45,450
So we asked her what she did, how she said it was amazing.

459
00:49:45,450 --> 00:49:50,040
I went down and we just looked at the Bank of the river and apparently the waterfall was coming back.

460
00:49:50,040 --> 00:49:56,550
So we cleared some of that, this or that other stuff there and cleared that bank and be able to take some of the mooring ropes away.

461
00:49:56,550 --> 00:50:00,810
We'll be able to get them back again. And then we learnt how to get the butterflies back for this area here.

462
00:50:00,810 --> 00:50:04,470
And I love all the trees were and I realise there's an otter which is up there.

463
00:50:04,470 --> 00:50:11,400
I had no idea about that. I met some fantastic people. We are big cake and we went down and had a cup of tea.

464
00:50:11,400 --> 00:50:17,790
But you did two and a half hours cardiovascular training, and you haven't mentioned that at all.

465
00:50:17,790 --> 00:50:23,970
Why, why should she mention it? Why do we have to do health as an extra thing?

466
00:50:23,970 --> 00:50:29,280
Health should be as part of normal things, health as a means to an end.

467
00:50:29,280 --> 00:50:33,810
The end is fulfilment and happiness. Health should never be the target end.

468
00:50:33,810 --> 00:50:37,350
It shouldn't be the end itself. It should always be the means to an end.

469
00:50:37,350 --> 00:50:47,430
Physical activity is definitely a means to an end because that lady has done more for her health, but she hasn't realised it for health by stealth.

470
00:50:47,430 --> 00:50:54,720
If you want to call it that way. And Sarah mentioned about being street, we've been doing,

471
00:50:54,720 --> 00:51:01,880
but we've now got over a million people who from the most deprived communities who've taken part and we make it a game.

472
00:51:01,880 --> 00:51:06,150
That thing is little RFID beatbox. We put those all around a city or town,

473
00:51:06,150 --> 00:51:14,100
and we give every single child in that area with all the schools a little RFID for if take it home and give it to their parents,

474
00:51:14,100 --> 00:51:18,830
our aunts and uncles and neighbours and workplaces get them.

475
00:51:18,830 --> 00:51:28,710
And before we know we have up to anything between 10 and 25 percent of the entire population playing a game, which I think How am I doing this game?

476
00:51:28,710 --> 00:51:34,980
This is great fun. And I say, go out and meet each other and talking to other people, they're exploring areas.

477
00:51:34,980 --> 00:51:40,290
We can bonus point so that people can go to the parks and green spaces and for six weeks.

478
00:51:40,290 --> 00:51:47,250
The world is transformed in that place. So Barnsley, thirty seven thousand people were playing in Hounslow.

479
00:51:47,250 --> 00:51:53,850
We've just finished there, twenty six thousand people playing, and we know that all sorts of things have taken place.

480
00:51:53,850 --> 00:51:59,010
But the most important thing is the most deprived communities are the ones that benefit the most.

481
00:51:59,010 --> 00:52:04,230
Because it's not health. We don't mention health. Public health pass,

482
00:52:04,230 --> 00:52:12,330
actually for them is about a game and opportunity for the future of going to the parks they just discovered and learning new things.

483
00:52:12,330 --> 00:52:15,960
And here in Hounslow, how's the traffic?

484
00:52:15,960 --> 00:52:21,420
People put a camera up for street to find out what happened before and after street for six weeks.

485
00:52:21,420 --> 00:52:28,800
You can see the gradual decline of House of Cars and vans as more people want to walk to school because

486
00:52:28,800 --> 00:52:36,210
that's becomes the norm because everyone's trying to get more points for their school and gaming is a game.

487
00:52:36,210 --> 00:52:41,550
Now at the bottom, we've seen even after a year that you sustain that behaviour because now the mum

488
00:52:41,550 --> 00:52:47,810
or dad has actually had quality time with their child and it's worked very well.

489
00:52:47,810 --> 00:52:55,670
So what started off as prises becomes looking at the environment, meeting up with friends, feeling good about yourself?

490
00:52:55,670 --> 00:53:04,400
The prises were there just to get it going. Let's put those away now, so let's have a quick recap of his fourth revolution.

491
00:53:04,400 --> 00:53:12,470
We've got resilience down the left hand side of strong social networks that place feeling secure, connexion type of purpose.

492
00:53:12,470 --> 00:53:19,400
If that's weak, then stressful events create chronic stress, and chronic stress has that horrible effect on poor diet,

493
00:53:19,400 --> 00:53:24,680
inactivity, alcohol, drugs, stress hormones and come out visceral fat forms.

494
00:53:24,680 --> 00:53:30,890
We haven't talked about the because then you've got that triad of disaster, of chronic inflammation, telomere shortening,

495
00:53:30,890 --> 00:53:40,280
mitochondrial damage leading in to all the health problems that we know in society, which will continue even if we've got the best medicine.

496
00:53:40,280 --> 00:53:49,990
Because as people live longer, we can have three or four of them and we'll have more and more and more people with diabetes improve that resilience.

497
00:53:49,990 --> 00:53:53,590
Strong social networks, beautiful place, connecting people together,

498
00:53:53,590 --> 00:53:58,450
giving people that sense of purpose and control over their own health and their life.

499
00:53:58,450 --> 00:54:02,860
Strong resilience, stressful events and now better off.

500
00:54:02,860 --> 00:54:08,620
And if we could do that, we'd get more satisfaction, happiness and healthy diet.

501
00:54:08,620 --> 00:54:13,940
So thank you very much. I'll leave that with you. But the fourth revolution?

502
00:54:13,940 --> 00:54:23,660
Is where human beings in the communities, in groups just like where we were in our origins of a hunter gatherer, take control of our health.

503
00:54:23,660 --> 00:54:37,240
Thank you very much. Thank you very much.

504
00:54:37,240 --> 00:54:43,060
It's fantastic and a lot of food for thought there. Do we have any questions?

505
00:54:43,060 --> 00:54:54,570
We've got a microphone, so if you want to put your hand up will weigh about you and then bring the microphone over and shout into them.

506
00:54:54,570 --> 00:55:06,870
Thank you very much. That was really amazing to see how well you could express something that we all kind of know, but not that well expressed.

507
00:55:06,870 --> 00:55:15,210
If I understood your weight right you, you are one of the main things you use as gamification in order to spread this.

508
00:55:15,210 --> 00:55:26,010
How do you spread this by itself, from community to community without having somebody like you have to be there and instil it?

509
00:55:26,010 --> 00:55:33,090
How do you make this so it spreads like a virus across the world?

510
00:55:33,090 --> 00:55:42,300
That's a great question, and I think we've used streets as an experimental to really learn what it is that drives people to makes their life change.

511
00:55:42,300 --> 00:55:50,250
So from that, I wouldn't expect you have beat the streets in every place on the planet so that we can try and get people to do it.

512
00:55:50,250 --> 00:55:56,160
But I think the example of the green gym is you go to where people are in that,

513
00:55:56,160 --> 00:56:00,330
what they believe in, what their values are and trying to understand that.

514
00:56:00,330 --> 00:56:06,210
And what we found for most people doing street is that they want to do something for their children.

515
00:56:06,210 --> 00:56:10,110
They didn't care about themselves. They want to do something for their children.

516
00:56:10,110 --> 00:56:16,280
They want to do something for their community. And they want to keep learning and understanding things.

517
00:56:16,280 --> 00:56:22,710
And by making something very local, ultra local. So there's no bus ride, but they can do something there.

518
00:56:22,710 --> 00:56:30,200
And then whether it's learning some craft or doing the conservation work or going for a short walk

519
00:56:30,200 --> 00:56:35,840
on a lead walk that is enough to get them out of their cycle of being indoors the whole time.

520
00:56:35,840 --> 00:56:39,500
And the thing that will get them going will be something which is not health,

521
00:56:39,500 --> 00:56:43,760
which is not physical activity, which is not one hundred and fifty minutes is not 10000 steps,

522
00:56:43,760 --> 00:56:50,060
but it's something because my grandchild told me to do it because I want to go back to the old place I used to work.

523
00:56:50,060 --> 00:56:57,860
I want to go to a football stadium where I support. So you're trying to make those things back to normal, so health gets lost.

524
00:56:57,860 --> 00:57:08,480
And what we've lost is that we put health centre stage and that we put health at the centre stage will always have the health inequalities,

525
00:57:08,480 --> 00:57:13,160
but instead, what do people want? How do they want their communities to work?

526
00:57:13,160 --> 00:57:17,720
Peter St. We've learnt a lot. The people want something very simple. They want a nice place to live.

527
00:57:17,720 --> 00:57:21,020
They want it to be comfortable. They want it to be good for their children.

528
00:57:21,020 --> 00:57:27,500
They want to be able to have green space around and they want to be able to walk without fear of cars.

529
00:57:27,500 --> 00:57:39,320
If we can try and get those values into people, then I think we can actually spread the understanding without having to be a game.

530
00:57:39,320 --> 00:57:44,570
I love the speech. Fantastic. Thank you. Oh, hello.

531
00:57:44,570 --> 00:57:50,720
Fantastic talk, I really enjoyed it. And like the other gentleman said, tell us a lot of interesting facts and things.

532
00:57:50,720 --> 00:57:58,910
One thing I was interested in is your your particular graph that demonstrated that as green space increased around where people lived,

533
00:57:58,910 --> 00:58:02,750
whether they were medium income or low income, their health increased.

534
00:58:02,750 --> 00:58:08,300
But I personally don't know of many places that are very green or pretty high green,

535
00:58:08,300 --> 00:58:14,900
where low income families are even able to live because by the time somewhere becomes very green at prices,

536
00:58:14,900 --> 00:58:18,290
low income families out, just that's the way our society works.

537
00:58:18,290 --> 00:58:23,720
If you look at inner city London, I can't think of a single area that is classed as low income that looks green.

538
00:58:23,720 --> 00:58:29,120
The moment it becomes green, it gentrified and those people can't live there anymore.

539
00:58:29,120 --> 00:58:39,440
So apart from gamification, which sounds fantastic and there have been attempts at it before, you know, and how do we how do we address that problem?

540
00:58:39,440 --> 00:58:45,110
So honestly, what's going on here on this study?

541
00:58:45,110 --> 00:58:50,000
They did, they did make sure that there was that accountability,

542
00:58:50,000 --> 00:58:54,990
but it was actually it wasn't just where the gentrification comes in actually goes up.

543
00:58:54,990 --> 00:58:56,330
So they allowed for that.

544
00:58:56,330 --> 00:59:06,170
Interesting when they did this in the states, it didn't show that relationship because in the states where you had green space,

545
00:59:06,170 --> 00:59:10,400
actually it meant you were in a suburban area and everyone was in the car.

546
00:59:10,400 --> 00:59:14,000
So there was no physical activity whatsoever. So there's zero physical activity.

547
00:59:14,000 --> 00:59:26,330
So that actually was a much, much flatter line. I think this is just been a new study is been done of of this and many other studies that was done,

548
00:59:26,330 --> 00:59:33,530
I think in The Lancet right last year where they actually took all the studies together to work out.

549
00:59:33,530 --> 00:59:44,840
And they did show that if you do plant up or you have what's perceived to be a safer area of green space, it does reduce inequalities.

550
00:59:44,840 --> 00:59:53,300
It does help many things on the on the health front. So it's just by increasing the greenery in a way that people understand it.

551
00:59:53,300 --> 01:00:01,250
So you don't want to have shades of people or people hiding behind hedges and things like that by intervening, it does make a difference.

552
01:00:01,250 --> 01:00:06,680
So I think there is a better part of understanding what greenery counts,

553
01:00:06,680 --> 01:00:10,700
what it is, and obviously a lot of studies and people have been working on that.

554
01:00:10,700 --> 01:00:16,970
But there does seem to be that you can make it as an intervention and you don't need to gentrify it just by having a greenery,

555
01:00:16,970 --> 01:00:20,810
because this can be a big housing estates where you can actually increase the

556
01:00:20,810 --> 01:00:26,930
greenery incredible edible who've been doing in vegetable work or around Tadcaster,

557
01:00:26,930 --> 01:00:34,250
etc. They've shown that you can actually improve a housing estate with greenery and keep the people there and keep those benefits.

558
01:00:34,250 --> 01:00:42,650
So I think it's understanding what part of greenery is, what value to what the dose is, how it's planned, how it's marked.

559
01:00:42,650 --> 01:00:49,490
I think we're still a long way away from knowing exactly what the prescription is in a way to a place where people live to make it better.

560
01:00:49,490 --> 01:01:03,160
But I do believe from what we've seen and the evidence, and I get that study up, but it is some value we can do that.

561
01:01:03,160 --> 01:01:14,380
Hello, thank you. And I was wondering what the evaluation showed from using these plant gardens or these green gyms to increase dietary,

562
01:01:14,380 --> 01:01:20,710
you know, productive dietary outcomes of dietary changes over the long term after they had partaking in these activities.

563
01:01:20,710 --> 01:01:30,130
And if there were sort of measurable circumstances that you saw through using that method that led people to actually choose better options available?

564
01:01:30,130 --> 01:01:32,170
No, we haven't done any any of that research.

565
01:01:32,170 --> 01:01:40,810
So two things about the diet and it's slightly out of my area because of dietary side is not my my strong point physical activity much more.

566
01:01:40,810 --> 01:01:47,860
But I do know that when you are active and reduce when you're stressed and inactive and obese,

567
01:01:47,860 --> 01:01:52,420
the grilling and the hormones of change make you choose the wrong foods.

568
01:01:52,420 --> 01:01:59,290
You tend to go for the high calories and refined carbohydrates, and that that's is well known.

569
01:01:59,290 --> 01:02:07,150
So just by taking people's stress away, you can start to actually undo that and they can choose a slightly better diet.

570
01:02:07,150 --> 01:02:13,180
We've never done any studies on the green gym, on physical activity, and we don't know stress levels, but we obviously haven't chosen that.

571
01:02:13,180 --> 01:02:19,960
We haven't done anything about their dietary behaviour. I'd love to think that it changes, but we haven't got any evidence.

572
01:02:19,960 --> 01:02:29,020
But certainly, choice of foods is the thing that seems to change a lot when when physical activity starts and stress comes down.

573
01:02:29,020 --> 01:02:37,820
I'm afraid I can't answer that question. It's not been done as far as I know.

574
01:02:37,820 --> 01:02:42,820
That's one of the. I am.

575
01:02:42,820 --> 01:02:53,170
So my question and it has just been touched on a bit, is we know that you took about people place and purpose as central to inflammation in the body.

576
01:02:53,170 --> 01:02:57,160
But we do know that the food that you eat is also central to that.

577
01:02:57,160 --> 01:03:05,410
So I also wondered, I know you sort of just answered it, but within that, we know that across the UK there are food deserts,

578
01:03:05,410 --> 01:03:11,980
nutrition deserts where people can't access fresh, healthy foods that would help with the inflammation in their body.

579
01:03:11,980 --> 01:03:15,760
So I just wondered what your thoughts were around addressing that?

580
01:03:15,760 --> 01:03:20,680
Yeah, I mean, I didn't go into the the food side because it would have taken it too long.

581
01:03:20,680 --> 01:03:29,720
And this was not my strongest point that you saw on the on this one here.

582
01:03:29,720 --> 01:03:39,590
Is. The unhealthy gut microbial and obviously we now know that the gut brain axis and how the microbes.

583
01:03:39,590 --> 01:03:46,520
Forty five percent of our cells in our body belong to bacteria, as we know from the gut.

584
01:03:46,520 --> 01:03:50,810
So it is a hugely important site and what we eat makes a vast difference,

585
01:03:50,810 --> 01:03:57,790
but also how that gut bacteria is laid down really from in utero and when we have when we're born.

586
01:03:57,790 --> 01:04:03,350
And so even if you're having a caesarian section, your gut microbiome will be different than if you had a normal vaginal delivery.

587
01:04:03,350 --> 01:04:12,650
So we should be going right back there for dietary changes of understanding antibiotics under the age of six months probably has major bigger effects,

588
01:04:12,650 --> 01:04:23,330
and you've ever thought through the dietary side is in a way starts before we've even eaten anything because of getting a gut bacteria, right?

589
01:04:23,330 --> 01:04:27,830
Because you become better resilience when you got the gut bacteria all healthy.

590
01:04:27,830 --> 01:04:29,270
But you're absolutely right.

591
01:04:29,270 --> 01:04:37,670
There is a real problem in nutrition, and I think to have the holiday hunger programmes across Britain is absolutely disgraceful.

592
01:04:37,670 --> 01:04:45,290
I just find it most horrific thing that people don't have enough money to be able to have a normal good diet for their children during the holidays.

593
01:04:45,290 --> 01:04:52,220
And we have to have these holiday hunger programmes. Otherwise it will just be refined carbohydrates and that's all they be eating.

594
01:04:52,220 --> 01:04:58,820
So it is important growing, I think, as always, have to be a perception as this whole thing about growing your own food.

595
01:04:58,820 --> 01:05:03,920
I would be very surprised that people would be able to continue with that in some of the very deprived areas.

596
01:05:03,920 --> 01:05:09,320
We just have to ensure that good food is much easier to get.

597
01:05:09,320 --> 01:05:21,170
But actually getting people's choice and making sure that they don't have to crave for the refined carbohydrates is probably as important as well.

598
01:05:21,170 --> 01:05:28,490
A gentleman in the red jacket in the middle. Thank you.

599
01:05:28,490 --> 01:05:37,460
Can we go virtual and it's going to be relevant, in other words, should my screensaver be a tree, should it come on every 10 minutes?

600
01:05:37,460 --> 01:05:41,440
And should I have a tree picture on my on my office wall of cities?

601
01:05:41,440 --> 01:05:42,440
Not to be trees all the time,

602
01:05:42,440 --> 01:05:49,610
but I'm just wondering whether virtual actually could be a difference and whether that could be a way of scaling up really dramatically.

603
01:05:49,610 --> 01:05:58,130
Yeah. Well, I hate to say this, but the evidence is it's very, very effective.

604
01:05:58,130 --> 01:06:10,100
So I have the motivation. Yeah, and and I know a lot of the exciting work going on for older people who are doing virtual walks with VR,

605
01:06:10,100 --> 01:06:15,350
virtual reality and the little thing they do have to get their feet off the ground.

606
01:06:15,350 --> 01:06:21,620
They just shuffle back to the forwards and they can do walks with friends and they can go to places they used to go as a child.

607
01:06:21,620 --> 01:06:25,820
And it's all done in virtual reality from our sitting room. So if they can't go out.

608
01:06:25,820 --> 01:06:30,920
So I, you know, there's one part of you says, well, as dreadful because they should be out.

609
01:06:30,920 --> 01:06:37,100
But if they can't get out right, because they're getting some activity and they're reliving an experience you used to have.

610
01:06:37,100 --> 01:06:42,860
But having green pictures in operating theatres makes a difference in recovery.

611
01:06:42,860 --> 01:06:49,130
Having your screensaver makes Microsoft have obviously done it well with the screen savers that they've got that.

612
01:06:49,130 --> 01:06:56,150
Yeah. All the virtual stuff. It does work, but the real stuff is better.

613
01:06:56,150 --> 01:07:05,150
I think I've got a microphone, so to speak. I'm part of the deprivation that you were talking about a few moments ago.

614
01:07:05,150 --> 01:07:13,100
Holiday hunger, food banks and all the rest of it is a political choice that's been made in this country over the past 10 years or so.

615
01:07:13,100 --> 01:07:19,070
So how are you taking your programme to government, both national government and local government?

616
01:07:19,070 --> 01:07:26,930
Because there's a lot of persuading to do that. I mean, we've been sponsored by Sport England,

617
01:07:26,930 --> 01:07:34,310
and some of the Sport England have got a very high target of reaching the most deprived communities and getting more active.

618
01:07:34,310 --> 01:07:35,810
And they're really struggling.

619
01:07:35,810 --> 01:07:44,570
They're really struggling to get sport and physical activity and get the people in a very deprived communities to be able to take take part.

620
01:07:44,570 --> 01:07:51,830
Luckily, the chief executive now banning the words hard to reach because it's our problem, not their problem.

621
01:07:51,830 --> 01:07:57,410
And I think we have to realise that way. We've been doing things in the past been quite patronising and wrong.

622
01:07:57,410 --> 01:08:01,790
When we come into a place, we get them with all the schools on board.

623
01:08:01,790 --> 01:08:04,700
We get a huge amount of ownership.

624
01:08:04,700 --> 01:08:12,470
What we're struggling to do is to get the government and the NHS, particularly to show that actually it can be done.

625
01:08:12,470 --> 01:08:20,060
You can actually invest is quite a bit is quite the ability to get people engaged in healthy living and healthy activities.

626
01:08:20,060 --> 01:08:26,630
But we can't do it in the way we used to do it, which is probably more of a top down and little scheme.

627
01:08:26,630 --> 01:08:29,480
This has got to be come from a community upwards, community owning it,

628
01:08:29,480 --> 01:08:33,590
community enjoying it, not mentioning health, not mentioning some of the things,

629
01:08:33,590 --> 01:08:40,310
but just to get people to do to just bring out their own ingenuity and understanding and doing

630
01:08:40,310 --> 01:08:47,000
things to their children and doing things in their local area so we can start to build it up.

631
01:08:47,000 --> 01:08:53,090
We go away and we know as some sustainability that lasts for over a year because we've gone there,

632
01:08:53,090 --> 01:08:57,500
but we're all trying to get the dietary side into it. We're trying to get some of the other things.

633
01:08:57,500 --> 01:09:02,210
We find the public health, sometimes just not quite getting it.

634
01:09:02,210 --> 01:09:08,870
I can understand that, but I think in some areas the public health is still struggling to know how to deal with it.

635
01:09:08,870 --> 01:09:12,060
And I I think I think we're still struggling to do it.

636
01:09:12,060 --> 01:09:17,090
But you're right. Politically, it has been a problem, but there's still a lot of people who don't,

637
01:09:17,090 --> 01:09:22,100
I don't think understand that this is a this is possible and you can make it happen,

638
01:09:22,100 --> 01:09:29,210
but you have to invest in these places to make infrastructure better and get people to own the problem themselves and build it up.

639
01:09:29,210 --> 01:09:30,580
I'm not sure that's a very good answer.

640
01:09:30,580 --> 01:09:43,970
A lot of great politicians on that, but that helps the big Jones just feedback on anything that looks like Lady Health.

641
01:09:43,970 --> 01:09:49,520
My question was going to be someone that was actually what is the role for Public Health England from a policy perspective.

642
01:09:49,520 --> 01:09:55,040
But linked to that, obviously Public Health England and its policies trickle down to the GP surgery.

643
01:09:55,040 --> 01:10:06,320
Is there not a critical role for GP surgeries and the practise of GP's and the surgery environment somehow in actually generating this process?

644
01:10:06,320 --> 01:10:13,250
I think there's massive change. I mean, I think GP's roles are going to have to change dramatically if we're going to make any headway at all.

645
01:10:13,250 --> 01:10:19,250
They're going to have to become we are going to have to become public health consultants as well and take

646
01:10:19,250 --> 01:10:25,370
the role of the surgery now in our facility and make that area an area which we have to look after,

647
01:10:25,370 --> 01:10:29,870
not just the people in it, but actually have an infrastructure change around it.

648
01:10:29,870 --> 01:10:37,490
KPMG's the patient groups are now beginning to get more teeth and some of them are starting to really understand how they can look after that area.

649
01:10:37,490 --> 01:10:44,330
And GP's started to say, No, you can't got to build a crossing, you've got to you can't build on that green space over there.

650
01:10:44,330 --> 01:10:49,550
So I think GP's are going to be vital for taking part, but of course, we're not trained.

651
01:10:49,550 --> 01:10:56,480
But I do think the moment that public health sits over their GP sit over here and we still haven't got that connexion.

652
01:10:56,480 --> 01:10:59,240
And I think it's way overdue that we get that right.

653
01:10:59,240 --> 01:11:05,880
And I think we're going to have to we're going to be forced to because otherwise we're unsustainable in our job.

654
01:11:05,880 --> 01:11:11,430
I, of course, the last few people have sort of taken the questions are going to ask.

655
01:11:11,430 --> 01:11:16,950
The last one was on the politics and we've got an election coming up and politicians of our money into the National Health Service.

656
01:11:16,950 --> 01:11:20,880
They even invent that they're going to build lots of hospitals and all this sort of stuff.

657
01:11:20,880 --> 01:11:29,130
So my spin on all this is how do you deal with all the vested interests that are vested in doing it differently from this?

658
01:11:29,130 --> 01:11:35,640
And also, can you have a little bit of explanation about the stress thing? I mean, there are lots and lots of things driving stress in modern living,

659
01:11:35,640 --> 01:11:40,350
whether it's people stuck on computers all day or it could be their jobs or their contracts,

660
01:11:40,350 --> 01:11:48,270
which kind of policies would you enact to sort of make modern living less stressful as it were?

661
01:11:48,270 --> 01:11:55,800
I invested interest in the health system in the TV and lots of places that are trying to drive us away from, you know,

662
01:11:55,800 --> 01:12:00,270
healthy living by since I said we'd be doing some work in a big bank,

663
01:12:00,270 --> 01:12:08,100
a very successful bank, it's money orientated and you've got all the commercial managers.

664
01:12:08,100 --> 01:12:17,190
And I started to talk about kindness in the office and started to talk about values and sympathy and understanding

665
01:12:17,190 --> 01:12:24,600
people where they're coming from and trying to make a place which is actually going to be much kinder.

666
01:12:24,600 --> 01:12:32,940
But for them to do tough work, really tough work where the pressure is still there, but they feel secure and they have.

667
01:12:32,940 --> 01:12:37,680
These top managers were talking about the girl who comes every mall, every Monday morning,

668
01:12:37,680 --> 01:12:41,910
and she talks and talks and talks about the television the night before and over the weekend.

669
01:12:41,910 --> 01:12:46,170
And what happened. I said, Oh my God, she's on again. And everyone was kind of, you know, eye rolling.

670
01:12:46,170 --> 01:12:51,540
And many realised that she never saw anyone all weekend. She had no friends, no family.

671
01:12:51,540 --> 01:12:57,510
And as a manager of an office where you're trying to get the best out of people, you're starting to see a shift.

672
01:12:57,510 --> 01:13:01,950
They're putting plants in there. They're doing birdsong in some of these managers.

673
01:13:01,950 --> 01:13:06,840
But I mean, these are things you'd never have heard of five years ago, 10 years ago.

674
01:13:06,840 --> 01:13:15,600
So I think we're starting to see the corporate sector beginning to take this and saying, look, stress is destroying our bottom line.

675
01:13:15,600 --> 01:13:20,160
How can we make people perform and be happier at work? So I think there's a line.

676
01:13:20,160 --> 01:13:27,120
I don't think you can actually impose it, I think. But I work at the NHS as an awful lot of catching up to do from the NHS.

677
01:13:27,120 --> 01:13:33,300
It's a very stressful environment and I think that we've got a long way to go on that.

678
01:13:33,300 --> 01:13:35,340
And then I think it's the infrastructure.

679
01:13:35,340 --> 01:13:42,300
I think the biggest thing we can do is to make places a better place to live, and that will be a vast amount of infrastructure change.

680
01:13:42,300 --> 01:13:48,970
A lot of money needs to do that, but a little bit how Liverpool was transformed when Hazeltine went up there made something.

681
01:13:48,970 --> 01:13:56,790
Yeah, I think every housing estate and everywhere where there's real danger, air quality is awful, where the roads are right by schools,

682
01:13:56,790 --> 01:14:05,280
we've just got to change it bit by bit with a 30 year plan to change our infrastructure of where those people who are struggling with stress leave.

683
01:14:05,280 --> 01:14:11,070
And I think that's probably the the easiest way we can. Well, not easiest, but the clearest way we can make a difference.

684
01:14:11,070 --> 01:14:21,180
And then I think the workplaces, the other. I think we're we're out of time for questions, obviously, we'll be going next door for drinks reception,

685
01:14:21,180 --> 01:14:29,280
so if you've got more questions, feel free to talk to him. Then if you've enjoyed this talk, please keep an eye on the Oxford Martin School website.

686
01:14:29,280 --> 01:14:34,710
We've got talks from Paul Nurse and Chris Whitty being announced imminently,

687
01:14:34,710 --> 01:14:59,702
and all that remains is for me to thank William for an excellent talk and lots to think about.
