1 00:00:01,357 --> 00:00:02,928 For a really long time, 2 00:00:02,952 --> 00:00:06,086 I had two mysteries that were hanging over me. 3 00:00:06,689 --> 00:00:08,950 I didn't understand them 4 00:00:08,974 --> 00:00:11,877 and, to be honest, I was quite afraid to look into them. 5 00:00:12,349 --> 00:00:15,896 The first mystery was, I'm 40 years old, 6 00:00:15,920 --> 00:00:18,991 and all throughout my lifetime, year after year, 7 00:00:19,015 --> 00:00:22,371 serious depression and anxiety have risen, 8 00:00:22,395 --> 00:00:25,085 in the United States, in Britain, 9 00:00:25,109 --> 00:00:26,863 and across the Western world. 10 00:00:27,173 --> 00:00:30,101 And I wanted to understand why. 11 00:00:31,108 --> 00:00:32,975 Why is this happening to us? 12 00:00:33,394 --> 00:00:36,036 Why is it that with each year that passes, 13 00:00:36,060 --> 00:00:39,314 more and more of us are finding it harder to get through the day? 14 00:00:39,743 --> 00:00:43,300 And I wanted to understand this because of a more personal mystery. 15 00:00:43,324 --> 00:00:44,713 When I was a teenager, 16 00:00:44,737 --> 00:00:46,158 I remember going to my doctor 17 00:00:46,182 --> 00:00:50,667 and explaining that I had this feeling, like pain was leaking out of me. 18 00:00:51,237 --> 00:00:52,633 I couldn't control it, 19 00:00:52,657 --> 00:00:54,942 I didn't understand why it was happening, 20 00:00:54,966 --> 00:00:57,021 I felt quite ashamed of it. 21 00:00:57,045 --> 00:00:58,641 And my doctor told me a story 22 00:00:58,665 --> 00:01:00,678 that I now realize was well-intentioned, 23 00:01:00,702 --> 00:01:02,394 but quite oversimplified. 24 00:01:02,418 --> 00:01:03,586 Not totally wrong. 25 00:01:03,610 --> 00:01:06,402 My doctor said, "We know why people get like this. 26 00:01:06,426 --> 00:01:10,658 Some people just naturally get a chemical imbalance in their heads -- 27 00:01:10,682 --> 00:01:12,103 you're clearly one of them. 28 00:01:12,127 --> 00:01:14,111 All we need to do is give you some drugs, 29 00:01:14,135 --> 00:01:16,499 it will get your chemical balance back to normal." 30 00:01:16,523 --> 00:01:18,933 So I started taking a drug called Paxil or Seroxat, 31 00:01:18,957 --> 00:01:21,983 it's the same thing with different names in different countries. 32 00:01:22,007 --> 00:01:24,490 And I felt much better, I got a real boost. 33 00:01:24,514 --> 00:01:25,925 But not very long afterwards, 34 00:01:25,949 --> 00:01:27,950 this feeling of pain started to come back. 35 00:01:27,974 --> 00:01:29,802 So I was given higher and higher doses 36 00:01:29,826 --> 00:01:33,037 until, for 13 years, I was taking the maximum possible dose 37 00:01:33,061 --> 00:01:35,077 that you're legally allowed to take. 38 00:01:35,402 --> 00:01:38,871 And for a lot of those 13 years, and pretty much all the time by the end, 39 00:01:38,895 --> 00:01:40,395 I was still in a lot of pain. 40 00:01:40,419 --> 00:01:43,395 And I started asking myself, "What's going on here? 41 00:01:43,419 --> 00:01:44,961 Because you're doing everything 42 00:01:44,985 --> 00:01:48,125 you're told to do by the story that's dominating the culture -- 43 00:01:48,149 --> 00:01:50,268 why do you still feel like this?" 44 00:01:50,292 --> 00:01:53,164 So to get to the bottom of these two mysteries, 45 00:01:53,188 --> 00:01:54,596 for a book that I've written 46 00:01:54,620 --> 00:01:57,125 I ended up going on a big journey all over the world, 47 00:01:57,149 --> 00:01:58,568 I traveled over 40,000 miles. 48 00:01:58,592 --> 00:02:01,085 I wanted to sit with the leading experts in the world 49 00:02:01,109 --> 00:02:03,276 about what causes depression and anxiety 50 00:02:03,300 --> 00:02:05,172 and crucially, what solves them, 51 00:02:05,196 --> 00:02:07,820 and people who have come through depression and anxiety 52 00:02:07,844 --> 00:02:09,956 and out the other side in all sorts of ways. 53 00:02:09,980 --> 00:02:11,466 And I learned a huge amount 54 00:02:11,490 --> 00:02:14,045 from the amazing people I got to know along the way. 55 00:02:14,069 --> 00:02:17,045 But I think at the heart of what I learned is, 56 00:02:17,069 --> 00:02:20,104 so far, we have scientific evidence 57 00:02:20,128 --> 00:02:23,835 for nine different causes of depression and anxiety. 58 00:02:23,859 --> 00:02:26,668 Two of them are indeed in our biology. 59 00:02:26,692 --> 00:02:29,375 Your genes can make you more sensitive to these problems, 60 00:02:29,399 --> 00:02:31,333 though they don't write your destiny. 61 00:02:31,357 --> 00:02:34,968 And there are real brain changes that can happen when you become depressed 62 00:02:34,992 --> 00:02:36,690 that can make it harder to get out. 63 00:02:36,714 --> 00:02:38,896 But most of the factors that have been proven 64 00:02:38,920 --> 00:02:40,761 to cause depression and anxiety 65 00:02:40,785 --> 00:02:42,550 are not in our biology. 66 00:02:43,520 --> 00:02:45,734 They are factors in the way we live. 67 00:02:46,116 --> 00:02:47,607 And once you understand them, 68 00:02:47,631 --> 00:02:50,727 it opens up a very different set of solutions 69 00:02:50,751 --> 00:02:52,299 that should be offered to people 70 00:02:52,323 --> 00:02:55,260 alongside the option of chemical antidepressants. 71 00:02:55,284 --> 00:02:57,077 For example, 72 00:02:57,101 --> 00:03:00,549 if you're lonely, you're more likely to become depressed. 73 00:03:00,573 --> 00:03:03,684 If, when you go to work, you don't have any control over your job, 74 00:03:03,708 --> 00:03:05,604 you've just got to do what you're told, 75 00:03:05,628 --> 00:03:07,517 you're more likely to become depressed. 76 00:03:07,541 --> 00:03:10,025 If you very rarely get out into the natural world, 77 00:03:10,049 --> 00:03:11,918 you're more likely to become depressed. 78 00:03:11,942 --> 00:03:15,053 And one thing unites a lot of the causes of depression and anxiety 79 00:03:15,077 --> 00:03:16,252 that I learned about. 80 00:03:16,276 --> 00:03:18,339 Not all of them, but a lot of them. 81 00:03:18,363 --> 00:03:20,029 Everyone here knows 82 00:03:20,053 --> 00:03:22,712 you've all got natural physical needs, right? 83 00:03:22,736 --> 00:03:23,910 Obviously. 84 00:03:23,934 --> 00:03:26,513 You need food, you need water, 85 00:03:26,537 --> 00:03:28,767 you need shelter, you need clean air. 86 00:03:28,791 --> 00:03:30,585 If I took those things away from you, 87 00:03:30,609 --> 00:03:32,902 you'd all be in real trouble, real fast. 88 00:03:32,926 --> 00:03:34,728 But at the same time, 89 00:03:34,752 --> 00:03:38,123 every human being has natural psychological needs. 90 00:03:38,147 --> 00:03:40,186 You need to feel you belong. 91 00:03:40,210 --> 00:03:43,274 You need to feel your life has meaning and purpose. 92 00:03:43,298 --> 00:03:45,829 You need to feel that people see you and value you. 93 00:03:45,853 --> 00:03:48,410 You need to feel you've got a future that makes sense. 94 00:03:48,434 --> 00:03:51,482 And this culture we built is good at lots of things. 95 00:03:51,506 --> 00:03:53,666 And many things are better than in the past -- 96 00:03:53,690 --> 00:03:55,011 I'm glad to be alive today. 97 00:03:55,035 --> 00:03:56,999 But we've been getting less and less good 98 00:03:57,023 --> 00:04:01,124 at meeting these deep, underlying psychological needs. 99 00:04:01,895 --> 00:04:03,998 And it's not the only thing that's going on, 100 00:04:04,022 --> 00:04:08,069 but I think it's the key reason why this crisis keeps rising and rising. 101 00:04:08,919 --> 00:04:12,149 And I found this really hard to absorb. 102 00:04:12,173 --> 00:04:14,879 I really wrestled with the idea 103 00:04:14,903 --> 00:04:19,309 of shifting from thinking of my depression as just a problem in my brain, 104 00:04:19,333 --> 00:04:20,500 to one with many causes, 105 00:04:20,524 --> 00:04:22,585 including many in the way we're living. 106 00:04:22,609 --> 00:04:24,974 And it only really began to fall into place for me 107 00:04:24,998 --> 00:04:28,141 when one day, I went to interview a South African psychiatrist 108 00:04:28,165 --> 00:04:29,966 named Dr. Derek Summerfield. 109 00:04:29,990 --> 00:04:31,141 He's a great guy. 110 00:04:31,165 --> 00:04:34,879 And Dr. Summerfield happened to be in Cambodia in 2001, 111 00:04:34,903 --> 00:04:38,196 when they first introduced chemical antidepressants 112 00:04:38,220 --> 00:04:39,952 for people in that country. 113 00:04:39,976 --> 00:04:43,273 And the local doctors, the Cambodians, had never heard of these drugs, 114 00:04:43,297 --> 00:04:44,888 so they were like, what are they? 115 00:04:44,912 --> 00:04:46,126 And he explained. 116 00:04:46,150 --> 00:04:47,682 And they said to him, 117 00:04:47,706 --> 00:04:50,403 "We don't need them, we've already got antidepressants." 118 00:04:50,427 --> 00:04:52,164 And he was like, "What do you mean?" 119 00:04:52,188 --> 00:04:55,427 He thought they were going to talk about some kind of herbal remedy, 120 00:04:55,451 --> 00:04:59,223 like St. John's Wort, ginkgo biloba, something like that. 121 00:04:59,910 --> 00:05:02,299 Instead, they told him a story. 122 00:05:02,800 --> 00:05:06,379 There was a farmer in their community who worked in the rice fields. 123 00:05:06,403 --> 00:05:08,173 And one day, he stood on a land mine 124 00:05:08,197 --> 00:05:10,387 left over from the war with the United States, 125 00:05:10,411 --> 00:05:11,823 and he got his leg blown off. 126 00:05:11,847 --> 00:05:13,283 So they him an artificial leg, 127 00:05:13,307 --> 00:05:16,078 and after a while, he went back to work in the rice fields. 128 00:05:16,102 --> 00:05:18,634 But apparently, it's super painful to work under water 129 00:05:18,658 --> 00:05:20,332 when you've got an artificial limb, 130 00:05:20,356 --> 00:05:22,276 and I'm guessing it was pretty traumatic 131 00:05:22,300 --> 00:05:24,879 to go back and work in the field where he got blown up. 132 00:05:24,903 --> 00:05:27,306 The guy started to cry all day, 133 00:05:27,330 --> 00:05:28,759 he refused to get out of bed, 134 00:05:28,783 --> 00:05:31,666 he developed all the symptoms of classic depression. 135 00:05:32,013 --> 00:05:33,378 The Cambodian doctor said, 136 00:05:33,402 --> 00:05:35,688 "This is when we gave him an antidepressant." 137 00:05:35,712 --> 00:05:38,347 And Dr. Summerfield said, "What was it?" 138 00:05:38,371 --> 00:05:41,180 They explained that they went and sat with him. 139 00:05:41,982 --> 00:05:43,382 They listened to him. 140 00:05:44,464 --> 00:05:47,011 They realized that his pain made sense -- 141 00:05:47,035 --> 00:05:49,956 it was hard for him to see it in the throes of his depression, 142 00:05:49,980 --> 00:05:53,640 but actually, it had perfectly understandable causes in his life. 143 00:05:53,966 --> 00:05:57,164 One of the doctors, talking to the people in the community, figured, 144 00:05:57,188 --> 00:05:59,125 "You know, if we bought this guy a cow, 145 00:05:59,149 --> 00:06:01,149 he could become a dairy farmer, 146 00:06:01,173 --> 00:06:04,268 he wouldn't be in this position that was screwing him up so much, 147 00:06:04,292 --> 00:06:06,799 he wouldn't have to go and work in the rice fields." 148 00:06:06,823 --> 00:06:08,022 So they bought him a cow. 149 00:06:08,046 --> 00:06:10,226 Within a couple of weeks, his crying stopped, 150 00:06:10,250 --> 00:06:12,162 within a month, his depression was gone. 151 00:06:12,186 --> 00:06:13,765 They said to doctor Summerfield, 152 00:06:13,789 --> 00:06:16,559 "So you see, doctor, that cow, that was an antidepressant, 153 00:06:16,583 --> 00:06:18,050 that's what you mean, right?" 154 00:06:18,074 --> 00:06:19,225 (Laughter) 155 00:06:19,249 --> 00:06:22,302 (Applause) 156 00:06:22,326 --> 00:06:25,199 If you'd been raised to think about depression the way I was, 157 00:06:25,223 --> 00:06:26,835 and most of the people here were, 158 00:06:26,859 --> 00:06:28,533 that sounds like a bad joke, right? 159 00:06:28,557 --> 00:06:30,581 "I went to my doctor for an antidepressant, 160 00:06:30,605 --> 00:06:31,771 she gave me a cow." 161 00:06:31,795 --> 00:06:34,822 But what those Cambodian doctors knew intuitively, 162 00:06:34,846 --> 00:06:37,823 based on this individual, unscientific anecdote, 163 00:06:37,847 --> 00:06:41,132 is what the leading medical body in the world, 164 00:06:41,156 --> 00:06:43,243 the World Health Organization, 165 00:06:43,267 --> 00:06:45,457 has been trying to tell us for years, 166 00:06:45,481 --> 00:06:47,973 based on the best scientific evidence. 167 00:06:48,576 --> 00:06:50,505 If you're depressed, 168 00:06:50,529 --> 00:06:51,906 if you're anxious, 169 00:06:53,008 --> 00:06:56,268 you're not weak, you're not crazy, 170 00:06:56,292 --> 00:06:59,877 you're not, in the main, a machine with broken parts. 171 00:07:00,950 --> 00:07:03,484 You're a human being with unmet needs. 172 00:07:03,919 --> 00:07:07,459 And it's just as important to think here about what those Cambodian doctors 173 00:07:07,483 --> 00:07:09,800 and the World Health Organization are not saying. 174 00:07:09,824 --> 00:07:11,356 They did not say to this farmer, 175 00:07:11,380 --> 00:07:14,181 "Hey, buddy, you need to pull yourself together. 176 00:07:14,205 --> 00:07:17,472 It's your job to figure out and fix this problem on your own." 177 00:07:17,851 --> 00:07:19,843 On the contrary, what they said is, 178 00:07:19,867 --> 00:07:23,391 "We're here as a group to pull together with you, 179 00:07:23,415 --> 00:07:27,827 so together, we can figure out and fix this problem." 180 00:07:28,543 --> 00:07:32,559 This is what every depressed person needs, 181 00:07:32,583 --> 00:07:35,828 and it's what every depressed person deserves. 182 00:07:35,852 --> 00:07:38,839 This is why one of the leading doctors at the United Nations, 183 00:07:38,863 --> 00:07:41,181 in their official statement for World Health Day, 184 00:07:41,205 --> 00:07:42,696 couple of years back in 2017, 185 00:07:42,720 --> 00:07:45,537 said we need to talk less about chemical imbalances 186 00:07:45,561 --> 00:07:48,618 and more about the imbalances in the way we live. 187 00:07:48,920 --> 00:07:50,893 Drugs give real relief to some people -- 188 00:07:50,917 --> 00:07:53,047 they gave relief to me for a while -- 189 00:07:53,071 --> 00:07:57,498 but precisely because this problem goes deeper than their biology, 190 00:07:57,522 --> 00:08:00,577 the solutions need to go much deeper, too. 191 00:08:00,601 --> 00:08:03,188 But when I first learned that, 192 00:08:03,212 --> 00:08:04,895 I remember thinking, 193 00:08:04,919 --> 00:08:07,045 "OK, I could see all the scientific evidence, 194 00:08:07,069 --> 00:08:08,641 I read a huge number of studies, 195 00:08:08,665 --> 00:08:11,971 I interviewed a huge number of the experts who were explaining this," 196 00:08:11,995 --> 00:08:14,381 but I kept thinking, "How can we possibly do that?" 197 00:08:14,405 --> 00:08:16,318 The things that are making us depressed 198 00:08:16,342 --> 00:08:18,833 are in most cases more complex than what was going on 199 00:08:18,857 --> 00:08:20,154 with this Cambodian farmer. 200 00:08:20,178 --> 00:08:22,812 Where do we even begin with that insight? 201 00:08:22,836 --> 00:08:26,085 But then, in the long journey for my book, 202 00:08:26,109 --> 00:08:27,680 all over the world, 203 00:08:27,704 --> 00:08:30,299 I kept meeting people who were doing exactly that, 204 00:08:30,323 --> 00:08:32,775 from Sydney, to San Francisco, 205 00:08:32,799 --> 00:08:33,971 to São Paulo. 206 00:08:33,995 --> 00:08:36,061 I kept meeting people who were understanding 207 00:08:36,085 --> 00:08:38,432 the deeper causes of depression and anxiety 208 00:08:38,456 --> 00:08:40,871 and, as groups, fixing them. 209 00:08:40,895 --> 00:08:43,576 Obviously, I can't tell you about all the amazing people 210 00:08:43,600 --> 00:08:45,076 I got to know and wrote about, 211 00:08:45,100 --> 00:08:48,553 or all of the nine causes of depression and anxiety that I learned about, 212 00:08:48,577 --> 00:08:51,059 because they won't let me give a 10-hour TED Talk -- 213 00:08:51,083 --> 00:08:52,835 you can complain about that to them. 214 00:08:52,859 --> 00:08:54,789 But I want to focus on two of the causes 215 00:08:54,813 --> 00:08:58,226 and two of the solutions that emerge from them, if that's alright. 216 00:08:58,578 --> 00:08:59,728 Here's the first. 217 00:09:00,285 --> 00:09:03,293 We are the loneliest society in human history. 218 00:09:03,317 --> 00:09:06,150 There was a recent study that asked Americans, 219 00:09:06,174 --> 00:09:09,324 "Do you feel like you're no longer close to anyone?" 220 00:09:09,348 --> 00:09:12,999 And 39 percent of people said that described them. 221 00:09:13,023 --> 00:09:14,387 "No longer close to anyone." 222 00:09:14,411 --> 00:09:16,908 In the international measurements of loneliness, 223 00:09:16,932 --> 00:09:19,490 Britain and the rest of Europe are just behind the US, 224 00:09:19,514 --> 00:09:21,299 in case anyone here is feeling smug. 225 00:09:21,323 --> 00:09:22,331 (Laughter) 226 00:09:22,355 --> 00:09:24,244 I spent a lot of time discussing this 227 00:09:24,268 --> 00:09:26,664 with the leading expert in the world on loneliness, 228 00:09:26,688 --> 00:09:28,942 an incredible man named professor John Cacioppo, 229 00:09:28,966 --> 00:09:30,117 who was at Chicago, 230 00:09:30,141 --> 00:09:32,964 and I thought a lot about one question his work poses to us. 231 00:09:32,988 --> 00:09:35,293 Professor Cacioppo asked, 232 00:09:35,317 --> 00:09:36,967 "Why do we exist? 233 00:09:36,991 --> 00:09:38,944 Why are we here, why are we alive?" 234 00:09:38,968 --> 00:09:41,174 One key reason 235 00:09:41,198 --> 00:09:44,015 is that our ancestors on the savannas of Africa 236 00:09:44,039 --> 00:09:45,759 were really good at one thing. 237 00:09:46,287 --> 00:09:49,577 They weren't bigger than the animals they took down a lot of the time, 238 00:09:49,601 --> 00:09:52,914 they weren't faster than the animals they took down a lot of the time, 239 00:09:52,938 --> 00:09:55,652 but they were much better at banding together into groups 240 00:09:55,676 --> 00:09:57,276 and cooperating. 241 00:09:57,300 --> 00:09:59,561 This was our superpower as a species -- 242 00:09:59,585 --> 00:10:00,990 we band together, 243 00:10:01,014 --> 00:10:03,490 just like bees evolved to live in a hive, 244 00:10:03,514 --> 00:10:05,746 humans evolved to live in a tribe. 245 00:10:05,770 --> 00:10:09,580 And we are the first humans ever 246 00:10:10,492 --> 00:10:11,959 to disband our tribes. 247 00:10:12,484 --> 00:10:14,551 And it is making us feel awful. 248 00:10:15,048 --> 00:10:17,192 But it doesn't have to be this way. 249 00:10:17,216 --> 00:10:19,850 One of the heroes in my book, and in fact, in my life, 250 00:10:19,874 --> 00:10:21,969 is a doctor named Sam Everington. 251 00:10:21,993 --> 00:10:24,731 He's a general practitioner in a poor part of East London, 252 00:10:24,755 --> 00:10:26,334 where I lived for many years. 253 00:10:26,358 --> 00:10:28,045 And Sam was really uncomfortable, 254 00:10:28,069 --> 00:10:29,625 because he had loads of patients 255 00:10:29,649 --> 00:10:32,093 coming to him with terrible depression and anxiety. 256 00:10:32,117 --> 00:10:34,839 And like me, he's not opposed to chemical antidepressants, 257 00:10:34,863 --> 00:10:37,085 he thinks they give some relief to some people. 258 00:10:37,109 --> 00:10:38,482 But he could see two things. 259 00:10:38,506 --> 00:10:42,061 Firstly, his patients were depressed and anxious a lot of the time 260 00:10:42,085 --> 00:10:45,823 for totally understandable reasons, like loneliness. 261 00:10:45,847 --> 00:10:49,291 And secondly, although the drugs were giving some relief to some people, 262 00:10:49,315 --> 00:10:51,583 for many people, they didn't solve the problem. 263 00:10:51,607 --> 00:10:53,140 The underlying problem. 264 00:10:53,871 --> 00:10:56,522 One day, Sam decided to pioneer a different approach. 265 00:10:56,546 --> 00:10:58,998 A woman came to his center, his medical center, 266 00:10:59,022 --> 00:11:00,489 called Lisa Cunningham. 267 00:11:00,513 --> 00:11:02,387 I got to know Lisa later. 268 00:11:02,411 --> 00:11:06,495 And Lisa had been shut away in her home with crippling depression and anxiety 269 00:11:06,519 --> 00:11:07,669 for seven years. 270 00:11:08,898 --> 00:11:11,823 And when she came to Sam's center, she was told, "Don't worry, 271 00:11:11,847 --> 00:11:13,677 we'll carry on giving you these drugs, 272 00:11:13,701 --> 00:11:16,498 but we're also going to prescribe something else. 273 00:11:16,522 --> 00:11:19,965 We're going to prescribe for you to come here to this center twice a week 274 00:11:19,989 --> 00:11:22,767 to meet with a group of other depressed and anxious people, 275 00:11:22,791 --> 00:11:25,601 not to talk about how miserable you are, 276 00:11:25,625 --> 00:11:29,172 but to figure out something meaningful you can all do together 277 00:11:29,196 --> 00:11:32,299 so you won't be lonely and you won't feel like life is pointless." 278 00:11:32,323 --> 00:11:35,098 The first time this group met, 279 00:11:35,122 --> 00:11:37,378 Lisa literally started vomiting with anxiety, 280 00:11:37,402 --> 00:11:39,323 it was so overwhelming for her. 281 00:11:39,347 --> 00:11:41,981 But people rubbed her back, the group started talking, 282 00:11:42,005 --> 00:11:43,680 they were like, "What could we do?" 283 00:11:43,704 --> 00:11:45,998 These are inner-city, East London people like me, 284 00:11:46,022 --> 00:11:48,070 they didn't know anything about gardening. 285 00:11:48,094 --> 00:11:50,339 They were like, "Why don't we learn gardening?" 286 00:11:50,363 --> 00:11:52,529 There was an area behind the doctors' offices 287 00:11:52,553 --> 00:11:53,704 that was just scrubland. 288 00:11:53,728 --> 00:11:55,610 "Why don't we make this into a garden?" 289 00:11:55,634 --> 00:11:57,809 They started to take books out of the library, 290 00:11:57,833 --> 00:11:59,318 started to watch YouTube clips. 291 00:11:59,342 --> 00:12:01,501 They started to get their fingers in the soil. 292 00:12:01,844 --> 00:12:04,887 They started to learn the rhythms of the seasons. 293 00:12:04,911 --> 00:12:06,241 There's a lot of evidence 294 00:12:06,265 --> 00:12:07,894 that exposure to the natural world 295 00:12:07,918 --> 00:12:09,894 is a really powerful antidepressant. 296 00:12:09,918 --> 00:12:12,927 But they started to do something even more important. 297 00:12:13,347 --> 00:12:15,377 They started to form a tribe. 298 00:12:15,401 --> 00:12:17,212 They started to form a group. 299 00:12:17,236 --> 00:12:19,260 They started to care about each other. 300 00:12:19,284 --> 00:12:20,958 If one of them didn't show up, 301 00:12:20,982 --> 00:12:23,502 the others would go looking for them -- "Are you OK?" 302 00:12:23,526 --> 00:12:26,137 Help them figure out what was troubling them that day. 303 00:12:26,161 --> 00:12:27,964 The way Lisa put it to me, 304 00:12:27,988 --> 00:12:30,585 "As the garden began to bloom, 305 00:12:30,609 --> 00:12:31,876 we began to bloom." 306 00:12:32,474 --> 00:12:34,506 This approach is called social prescribing, 307 00:12:34,530 --> 00:12:36,045 it's spreading all over Europe. 308 00:12:36,069 --> 00:12:38,370 And there's a small, but growing body of evidence 309 00:12:38,394 --> 00:12:41,274 suggesting it can produce real and meaningful falls 310 00:12:41,298 --> 00:12:43,276 in depression and anxiety. 311 00:12:43,300 --> 00:12:47,021 And one day, I remember standing in the garden 312 00:12:47,045 --> 00:12:49,526 that Lisa and her once-depressed friends had built -- 313 00:12:49,550 --> 00:12:51,134 it's a really beautiful garden -- 314 00:12:51,158 --> 00:12:52,349 and having this thought, 315 00:12:52,373 --> 00:12:56,244 it's very much inspired by a guy called professor Hugh Mackay in Australia. 316 00:12:56,268 --> 00:13:00,649 I was thinking, so often when people feel down in this culture, 317 00:13:00,673 --> 00:13:03,737 what we say to them -- I'm sure everyone here said it, I have -- 318 00:13:03,761 --> 00:13:06,985 we say, "You just need to be you, be yourself." 319 00:13:07,742 --> 00:13:10,692 And I've realized, actually, what we should say to people is, 320 00:13:10,716 --> 00:13:11,866 "Don't be you. 321 00:13:12,306 --> 00:13:13,639 Don't be yourself. 322 00:13:14,218 --> 00:13:16,427 Be us, be we. 323 00:13:16,765 --> 00:13:18,090 Be part of a group." 324 00:13:18,114 --> 00:13:21,820 (Applause) 325 00:13:21,844 --> 00:13:24,423 The solution to these problems 326 00:13:24,447 --> 00:13:27,598 does not lie in drawing more and more on your resources 327 00:13:27,622 --> 00:13:29,061 as an isolated individual -- 328 00:13:29,085 --> 00:13:31,125 that's partly what got us in this crisis. 329 00:13:31,149 --> 00:13:33,902 It lies on reconnecting with something bigger than you. 330 00:13:33,926 --> 00:13:36,347 And that really connects to one of the other causes 331 00:13:36,371 --> 00:13:39,268 of depression and anxiety that I wanted to talk to you about. 332 00:13:39,292 --> 00:13:40,982 So everyone knows 333 00:13:41,006 --> 00:13:44,752 junk food has taken over our diets and made us physically sick. 334 00:13:44,776 --> 00:13:46,982 I don't say that with any sense of superiority, 335 00:13:47,006 --> 00:13:49,405 I literally came to give this talk from McDonald's. 336 00:13:49,429 --> 00:13:52,942 I saw all of you eating that healthy TED breakfast, I was like no way. 337 00:13:52,966 --> 00:13:58,109 But just like junk food has taken over our diets and made us physically sick, 338 00:13:58,133 --> 00:14:02,243 a kind of junk values have taken over our minds 339 00:14:02,267 --> 00:14:03,745 and made us mentally sick. 340 00:14:04,157 --> 00:14:07,261 For thousands of years, philosophers have said, 341 00:14:07,285 --> 00:14:11,873 if you think life is about money, and status and showing off, 342 00:14:11,897 --> 00:14:13,420 you're going to feel like crap. 343 00:14:13,444 --> 00:14:15,511 That's not an exact quote from Schopenhauer, 344 00:14:15,535 --> 00:14:17,307 but that is the gist of what he said. 345 00:14:17,331 --> 00:14:20,357 But weirdly, hardy anyone had scientifically investigated this, 346 00:14:20,381 --> 00:14:24,030 until a truly extraordinary person I got to know, named professor Tim Kasser, 347 00:14:24,054 --> 00:14:26,347 who's at Knox College in Illinois, 348 00:14:26,371 --> 00:14:28,934 and he's been researching this for about 30 years now. 349 00:14:28,958 --> 00:14:31,974 And his research suggests several really important things. 350 00:14:31,998 --> 00:14:35,189 Firstly, the more you believe 351 00:14:35,213 --> 00:14:39,578 you can buy and display your way out of sadness, 352 00:14:39,602 --> 00:14:41,793 and into a good life, 353 00:14:41,817 --> 00:14:44,729 the more likely you are to become depressed and anxious. 354 00:14:44,753 --> 00:14:46,046 And secondly, 355 00:14:46,070 --> 00:14:50,658 as a society, we have become much more driven by these beliefs. 356 00:14:50,682 --> 00:14:52,095 All throughout my lifetime, 357 00:14:52,119 --> 00:14:56,312 under the weight of advertising and Instagram and everything like them. 358 00:14:56,871 --> 00:14:58,244 And as I thought about this, 359 00:14:58,268 --> 00:15:04,029 I realized it's like we've all been fed since birth, a kind of KFC for the soul. 360 00:15:04,053 --> 00:15:07,926 We've been trained to look for happiness in all the wrong places, 361 00:15:07,950 --> 00:15:10,720 and just like junk food doesn't meet your nutritional needs 362 00:15:10,744 --> 00:15:13,042 and actually makes you feel terrible, 363 00:15:13,066 --> 00:15:16,208 junk values don't meet your psychological needs, 364 00:15:16,232 --> 00:15:18,874 and they take you away from a good life. 365 00:15:18,898 --> 00:15:21,521 But when I first spent time with professor Kasser 366 00:15:21,545 --> 00:15:23,022 and I was learning all this, 367 00:15:23,046 --> 00:15:25,633 I felt a really weird mixture of emotions. 368 00:15:25,657 --> 00:15:28,347 Because on the one hand, I found this really challenging. 369 00:15:28,371 --> 00:15:31,633 I could see how often in my own life, when I felt down, 370 00:15:31,657 --> 00:15:36,922 I tried to remedy it with some kind of show-offy, grand external solution. 371 00:15:37,441 --> 00:15:40,131 And I could see why that did not work well for me. 372 00:15:40,930 --> 00:15:43,812 I also thought, isn't this kind of obvious? 373 00:15:43,836 --> 00:15:45,581 Isn't this almost like banal, right? 374 00:15:45,605 --> 00:15:46,930 If I said to everyone here, 375 00:15:46,954 --> 00:15:49,097 none of you are going to lie on your deathbed 376 00:15:49,121 --> 00:15:52,437 and think about all the shoes you bought and all the retweets you got, 377 00:15:52,461 --> 00:15:54,144 you're going to think about moments 378 00:15:54,168 --> 00:15:56,279 of love, meaning and connection in your life. 379 00:15:56,303 --> 00:15:58,248 I think that seems almost like a cliché. 380 00:15:58,272 --> 00:16:00,621 But I kept talking to professor Kasser and saying, 381 00:16:00,645 --> 00:16:02,998 "Why am I feeling this strange doubleness?" 382 00:16:03,022 --> 00:16:06,829 And he said, "At some level, we all know these things. 383 00:16:06,853 --> 00:16:09,228 But in this culture, we don't live by them." 384 00:16:09,252 --> 00:16:11,331 We know them so well they've become clichés, 385 00:16:11,355 --> 00:16:12,633 but we don't live by them. 386 00:16:12,657 --> 00:16:15,866 I kept asking why, why would we know something so profound, 387 00:16:15,890 --> 00:16:17,176 but not live by it? 388 00:16:17,200 --> 00:16:20,604 And after a while, professor Kasser said to me, 389 00:16:20,628 --> 00:16:23,049 "Because we live in a machine 390 00:16:23,073 --> 00:16:26,806 that is designed to get us to neglect what is important about life." 391 00:16:27,260 --> 00:16:28,847 I had to really think about that. 392 00:16:28,871 --> 00:16:30,276 "Because we live in a machine 393 00:16:30,300 --> 00:16:33,978 that is designed to get us to neglect what is important about life." 394 00:16:34,299 --> 00:16:38,077 And professor Kasser wanted to figure out if we can disrupt that machine. 395 00:16:38,101 --> 00:16:39,974 He's done loads of research into this; 396 00:16:39,998 --> 00:16:41,553 I'll tell you about one example, 397 00:16:41,577 --> 00:16:45,077 and I really urge everyone here to try this with their friends and family. 398 00:16:45,101 --> 00:16:48,443 With a guy called Nathan Dungan, he got a group of teenagers and adults 399 00:16:48,467 --> 00:16:52,680 to come together for a series of sessions over a period of time, to meet up. 400 00:16:52,704 --> 00:16:54,467 And part of the point of the group 401 00:16:54,491 --> 00:16:57,791 was to get people to think about a moment in their life 402 00:16:57,815 --> 00:17:00,561 they had actually found meaning and purpose. 403 00:17:00,585 --> 00:17:02,728 For different people, it was different things. 404 00:17:02,752 --> 00:17:06,369 For some people, it was playing music, writing, helping someone -- 405 00:17:06,393 --> 00:17:09,196 I'm sure everyone here can picture something, right? 406 00:17:09,220 --> 00:17:12,101 And part of the point of the group was to get people to ask, 407 00:17:12,125 --> 00:17:14,887 "OK, how could you dedicate more of your life 408 00:17:14,911 --> 00:17:17,595 to pursuing these moments of meaning and purpose, 409 00:17:17,619 --> 00:17:20,569 and less to, I don't know, buying crap you don't need, 410 00:17:20,593 --> 00:17:23,315 putting it on social media and trying to get people to go, 411 00:17:23,339 --> 00:17:24,606 'OMG, so jealous!'" 412 00:17:24,958 --> 00:17:26,601 And what they found was, 413 00:17:26,625 --> 00:17:27,959 just having these meetings, 414 00:17:27,983 --> 00:17:31,093 it was like a kind of Alcoholics Anonymous for consumerism, right? 415 00:17:31,807 --> 00:17:34,760 Getting people to have these meetings, articulate these values, 416 00:17:34,784 --> 00:17:37,315 determine to act on them and check in with each other, 417 00:17:37,339 --> 00:17:40,196 led to a marked shift in people's values. 418 00:17:40,220 --> 00:17:44,633 It took them away from this hurricane of depression-generating messages 419 00:17:44,657 --> 00:17:47,291 training us to seek happiness in the wrong places, 420 00:17:47,315 --> 00:17:50,656 and towards more meaningful and nourishing values 421 00:17:50,680 --> 00:17:52,680 that lift us out of depression. 422 00:17:53,347 --> 00:17:56,649 But with all the solutions that I saw and have written about, 423 00:17:56,673 --> 00:17:59,412 and many I can't talk about here, 424 00:17:59,436 --> 00:18:00,807 I kept thinking, 425 00:18:00,831 --> 00:18:04,530 you know: Why did it take me so long to see these insights? 426 00:18:04,554 --> 00:18:06,570 Because when you explain them to people -- 427 00:18:06,594 --> 00:18:09,038 some of them are more complicated, but not all -- 428 00:18:09,062 --> 00:18:12,306 when you explain this to people, it's not like rocket science, right? 429 00:18:12,330 --> 00:18:14,425 At some level, we already know these things. 430 00:18:14,449 --> 00:18:17,086 Why do we find it so hard to understand? 431 00:18:17,110 --> 00:18:19,044 I think there's many reasons. 432 00:18:19,475 --> 00:18:23,744 But I think one reason is that we have to change our understanding 433 00:18:23,768 --> 00:18:27,188 of what depression and anxiety actually are. 434 00:18:27,776 --> 00:18:29,958 There are very real biological contributions 435 00:18:29,982 --> 00:18:31,715 to depression and anxiety. 436 00:18:32,117 --> 00:18:35,871 But if we allow the biology to become the whole picture, 437 00:18:35,895 --> 00:18:37,141 as I did for so long, 438 00:18:37,165 --> 00:18:41,230 as I would argue our culture has done pretty much most of my life, 439 00:18:41,254 --> 00:18:45,111 what we're implicitly saying to people is, and this isn't anyone's intention, 440 00:18:45,135 --> 00:18:48,172 but what we're implicitly saying to people is, 441 00:18:48,196 --> 00:18:50,498 "Your pain doesn't mean anything. 442 00:18:50,522 --> 00:18:51,958 It's just a malfunction. 443 00:18:51,982 --> 00:18:54,451 It's like a glitch in a computer program, 444 00:18:54,475 --> 00:18:57,142 it's just a wiring problem in your head." 445 00:18:58,061 --> 00:19:01,168 But I was only able to start changing my life 446 00:19:01,192 --> 00:19:05,257 when I realized your depression is not a malfunction. 447 00:19:06,620 --> 00:19:07,770 It's a signal. 448 00:19:08,684 --> 00:19:10,691 Your depression is a signal. 449 00:19:11,077 --> 00:19:12,918 It's telling you something. 450 00:19:12,942 --> 00:19:17,553 (Applause) 451 00:19:17,577 --> 00:19:19,966 We feel this way for reasons, 452 00:19:19,990 --> 00:19:22,705 and they can be hard to see in the throes of depression -- 453 00:19:22,729 --> 00:19:25,339 I understand that really well from personal experience. 454 00:19:25,363 --> 00:19:28,846 But with the right help, we can understand these problems 455 00:19:28,870 --> 00:19:31,344 and we can fix these problems together. 456 00:19:31,368 --> 00:19:32,560 But to do that, 457 00:19:32,584 --> 00:19:34,322 the very first step 458 00:19:34,346 --> 00:19:36,964 is we have to stop insulting these signals 459 00:19:36,988 --> 00:19:41,180 by saying they're a sign of weakness, or madness or purely biological, 460 00:19:41,204 --> 00:19:43,139 except for a tiny number of people. 461 00:19:43,163 --> 00:19:46,789 We need to start listening to these signals, 462 00:19:46,813 --> 00:19:50,085 because they're telling us something we really need to hear. 463 00:19:50,514 --> 00:19:55,537 It's only when we truly listen to these signals, 464 00:19:55,561 --> 00:19:59,576 and we honor these signals and respect these signals, 465 00:19:59,600 --> 00:20:01,847 that we're going to begin to see 466 00:20:01,871 --> 00:20:06,029 the liberating, nourishing, deeper solutions. 467 00:20:07,133 --> 00:20:11,206 The cows that are waiting all around us. 468 00:20:11,585 --> 00:20:12,766 Thank you. 469 00:20:12,790 --> 00:20:16,478 (Applause)
