WEBVTT 00:00:01.357 --> 00:00:02.928 For a really long time, 00:00:02.952 --> 00:00:06.086 I had two mysteries that were hanging over me. 00:00:06.689 --> 00:00:08.950 I didn't understand them 00:00:08.974 --> 00:00:11.877 and, to be honest, I was quite afraid to look into them. 00:00:12.349 --> 00:00:15.896 The first mystery was, I'm 40 years old, 00:00:15.920 --> 00:00:18.991 and all throughout my lifetime, year after year, 00:00:19.015 --> 00:00:22.371 serious depression and anxiety have risen, 00:00:22.395 --> 00:00:25.085 in the United States, in Britain, 00:00:25.109 --> 00:00:26.863 and across the Western world. 00:00:27.173 --> 00:00:30.101 And I wanted to understand why. 00:00:31.108 --> 00:00:32.975 Why is this happening to us? 00:00:33.394 --> 00:00:36.036 Why is it that with each year that passes, 00:00:36.060 --> 00:00:39.314 more and more of us are finding it harder to get through the day? 00:00:39.743 --> 00:00:43.300 And I wanted to understand this because of a more personal mystery. NOTE Paragraph 00:00:43.324 --> 00:00:44.713 When I was a teenager, 00:00:44.737 --> 00:00:46.158 I remember going to my doctor 00:00:46.182 --> 00:00:50.667 and explaining that I had this feeling, like pain was leaking out of me. 00:00:51.237 --> 00:00:52.633 I couldn't control it, 00:00:52.657 --> 00:00:54.942 I didn't understand why it was happening, 00:00:54.966 --> 00:00:57.021 I felt quite ashamed of it. 00:00:57.045 --> 00:00:58.641 And my doctor told me a story 00:00:58.665 --> 00:01:00.678 that I now realize was well-intentioned, 00:01:00.702 --> 00:01:02.394 but quite oversimplified. 00:01:02.418 --> 00:01:03.586 Not totally wrong. 00:01:03.610 --> 00:01:06.402 My doctor said, "We know why people get like this. 00:01:06.426 --> 00:01:10.658 Some people just naturally get a chemical imbalance in their heads -- 00:01:10.682 --> 00:01:12.103 you're clearly one of them. 00:01:12.127 --> 00:01:14.111 All we need to do is give you some drugs, 00:01:14.135 --> 00:01:16.499 it will get your chemical balance back to normal." NOTE Paragraph 00:01:16.523 --> 00:01:18.933 So I started taking a drug called Paxil or Seroxat, 00:01:18.957 --> 00:01:21.983 it's the same thing with different names in different countries. 00:01:22.007 --> 00:01:24.490 And I felt much better, I got a real boost. 00:01:24.514 --> 00:01:25.925 But not very long afterwards, 00:01:25.949 --> 00:01:27.950 this feeling of pain started to come back. 00:01:27.974 --> 00:01:29.802 So I was given higher and higher doses 00:01:29.826 --> 00:01:33.037 until, for 13 years, I was taking the maximum possible dose 00:01:33.061 --> 00:01:35.077 that you're legally allowed to take. 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, 00:01:38.895 --> 00:01:40.395 I was still in a lot of pain. 00:01:40.419 --> 00:01:43.395 And I started asking myself, "What's going on here? 00:01:43.419 --> 00:01:44.961 Because you're doing everything 00:01:44.985 --> 00:01:48.125 you're told to do by the story that's dominating the culture -- 00:01:48.149 --> 00:01:50.268 why do you still feel like this?" NOTE Paragraph 00:01:50.292 --> 00:01:53.164 So to get to the bottom of these two mysteries, 00:01:53.188 --> 00:01:54.596 for a book that I've written 00:01:54.620 --> 00:01:57.125 I ended up going on a big journey all over the world, 00:01:57.149 --> 00:01:58.568 I traveled over 40,000 miles. 00:01:58.592 --> 00:02:01.085 I wanted to sit with the leading experts in the world 00:02:01.109 --> 00:02:03.276 about what causes depression and anxiety 00:02:03.300 --> 00:02:05.172 and crucially, what solves them, 00:02:05.196 --> 00:02:07.820 and people who have come through depression and anxiety 00:02:07.844 --> 00:02:09.956 and out the other side in all sorts of ways. 00:02:09.980 --> 00:02:11.466 And I learned a huge amount 00:02:11.490 --> 00:02:14.045 from the amazing people I got to know along the way. NOTE Paragraph 00:02:14.069 --> 00:02:17.045 But I think at the heart of what I learned is, 00:02:17.069 --> 00:02:20.104 so far, we have scientific evidence 00:02:20.128 --> 00:02:23.835 for nine different causes of depression and anxiety. 00:02:23.859 --> 00:02:26.668 Two of them are indeed in our biology. 00:02:26.692 --> 00:02:29.375 Your genes can make you more sensitive to these problems, 00:02:29.399 --> 00:02:31.333 though they don't write your destiny. 00:02:31.357 --> 00:02:34.968 And there are real brain changes that can happen when you become depressed 00:02:34.992 --> 00:02:36.690 that can make it harder to get out. 00:02:36.714 --> 00:02:38.896 But most of the factors that have been proven 00:02:38.920 --> 00:02:40.761 to cause depression and anxiety 00:02:40.785 --> 00:02:42.550 are not in our biology. 00:02:43.520 --> 00:02:45.734 They are factors in the way we live. 00:02:46.116 --> 00:02:47.607 And once you understand them, 00:02:47.631 --> 00:02:50.727 it opens up a very different set of solutions 00:02:50.751 --> 00:02:52.299 that should be offered to people 00:02:52.323 --> 00:02:55.260 alongside the option of chemical antidepressants. NOTE Paragraph 00:02:55.284 --> 00:02:57.077 For example, 00:02:57.101 --> 00:03:00.549 if you're lonely, you're more likely to become depressed. 00:03:00.573 --> 00:03:03.684 If, when you go to work, you don't have any control over your job, 00:03:03.708 --> 00:03:05.604 you've just got to do what you're told, 00:03:05.628 --> 00:03:07.517 you're more likely to become depressed. 00:03:07.541 --> 00:03:10.025 If you very rarely get out into the natural world, 00:03:10.049 --> 00:03:11.918 you're more likely to become depressed. NOTE Paragraph 00:03:11.942 --> 00:03:15.053 And one thing unites a lot of the causes of depression and anxiety 00:03:15.077 --> 00:03:16.252 that I learned about. 00:03:16.276 --> 00:03:18.339 Not all of them, but a lot of them. 00:03:18.363 --> 00:03:20.029 Everyone here knows 00:03:20.053 --> 00:03:22.712 you've all got natural physical needs, right? 00:03:22.736 --> 00:03:23.910 Obviously. 00:03:23.934 --> 00:03:26.513 You need food, you need water, 00:03:26.537 --> 00:03:28.767 you need shelter, you need clean air. 00:03:28.791 --> 00:03:30.585 If I took those things away from you, 00:03:30.609 --> 00:03:32.902 you'd all be in real trouble, real fast. 00:03:32.926 --> 00:03:34.728 But at the same time, 00:03:34.752 --> 00:03:38.123 every human being has natural psychological needs. 00:03:38.147 --> 00:03:40.186 You need to feel you belong. 00:03:40.210 --> 00:03:43.274 You need to feel your life has meaning and purpose. 00:03:43.298 --> 00:03:45.829 You need to feel that people see you and value you. 00:03:45.853 --> 00:03:48.410 You need to feel you've got a future that makes sense. 00:03:48.434 --> 00:03:51.482 And this culture we built is good at lots of things. 00:03:51.506 --> 00:03:53.666 And many things are better than in the past -- 00:03:53.690 --> 00:03:55.011 I'm glad to be alive today. 00:03:55.035 --> 00:03:56.999 But we've been getting less and less good 00:03:57.023 --> 00:04:01.124 at meeting these deep, underlying psychological needs. 00:04:01.895 --> 00:04:03.998 And it's not the only thing that's going on, 00:04:04.022 --> 00:04:08.069 but I think it's the key reason why this crisis keeps rising and rising. 00:04:08.919 --> 00:04:12.149 And I found this really hard to absorb. 00:04:12.173 --> 00:04:14.879 I really wrestled with the idea 00:04:14.903 --> 00:04:19.309 of shifting from thinking of my depression as just a problem in my brain, 00:04:19.333 --> 00:04:20.500 to one with many causes, 00:04:20.524 --> 00:04:22.585 including many in the way we're living. NOTE Paragraph 00:04:22.609 --> 00:04:24.974 And it only really began to fall into place for me 00:04:24.998 --> 00:04:28.141 when one day, I went to interview a South African psychiatrist 00:04:28.165 --> 00:04:29.966 named Dr. Derek Summerfield. 00:04:29.990 --> 00:04:31.141 He's a great guy. 00:04:31.165 --> 00:04:34.879 And Dr. Summerfield happened to be in Cambodia in 2001, 00:04:34.903 --> 00:04:38.196 when they first introduced chemical antidepressants 00:04:38.220 --> 00:04:39.952 for people in that country. 00:04:39.976 --> 00:04:43.273 And the local doctors, the Cambodians, had never heard of these drugs, 00:04:43.297 --> 00:04:44.888 so they were like, what are they? 00:04:44.912 --> 00:04:46.126 And he explained. 00:04:46.150 --> 00:04:47.682 And they said to him, 00:04:47.706 --> 00:04:50.403 "We don't need them, we've already got antidepressants." 00:04:50.427 --> 00:04:52.164 And he was like, "What do you mean?" 00:04:52.188 --> 00:04:55.427 He thought they were going to talk about some kind of herbal remedy, 00:04:55.451 --> 00:04:59.223 like St. John's Wort, ginkgo biloba, something like that. 00:04:59.910 --> 00:05:02.299 Instead, they told him a story. NOTE Paragraph 00:05:02.800 --> 00:05:06.379 There was a farmer in their community who worked in the rice fields. 00:05:06.403 --> 00:05:08.173 And one day, he stood on a land mine 00:05:08.197 --> 00:05:10.387 left over from the war with the United States, 00:05:10.411 --> 00:05:11.823 and he got his leg blown off. 00:05:11.847 --> 00:05:13.283 So they him an artificial leg, 00:05:13.307 --> 00:05:16.078 and after a while, he went back to work in the rice fields. 00:05:16.102 --> 00:05:18.634 But apparently, it's super painful to work under water 00:05:18.658 --> 00:05:20.332 when you've got an artificial limb, 00:05:20.356 --> 00:05:22.276 and I'm guessing it was pretty traumatic 00:05:22.300 --> 00:05:24.879 to go back and work in the field where he got blown up. 00:05:24.903 --> 00:05:27.306 The guy started to cry all day, 00:05:27.330 --> 00:05:28.759 he refused to get out of bed, 00:05:28.783 --> 00:05:31.666 he developed all the symptoms of classic depression. 00:05:32.013 --> 00:05:33.378 The Cambodian doctor said, 00:05:33.402 --> 00:05:35.688 "This is when we gave him an antidepressant." 00:05:35.712 --> 00:05:38.347 And Dr. Summerfield said, "What was it?" 00:05:38.371 --> 00:05:41.180 They explained that they went and sat with him. 00:05:41.982 --> 00:05:43.382 They listened to him. 00:05:44.464 --> 00:05:47.011 They realized that his pain made sense -- 00:05:47.035 --> 00:05:49.956 it was hard for him to see it in the throes of his depression, 00:05:49.980 --> 00:05:53.640 but actually, it had perfectly understandable causes in his life. 00:05:53.966 --> 00:05:57.164 One of the doctors, talking to the people in the community, figured, 00:05:57.188 --> 00:05:59.125 "You know, if we bought this guy a cow, 00:05:59.149 --> 00:06:01.149 he could become a dairy farmer, 00:06:01.173 --> 00:06:04.268 he wouldn't be in this position that was screwing him up so much, 00:06:04.292 --> 00:06:06.799 he wouldn't have to go and work in the rice fields." 00:06:06.823 --> 00:06:08.022 So they bought him a cow. 00:06:08.046 --> 00:06:10.226 Within a couple of weeks, his crying stopped, 00:06:10.250 --> 00:06:12.162 within a month, his depression was gone. 00:06:12.186 --> 00:06:13.765 They said to doctor Summerfield, 00:06:13.789 --> 00:06:16.559 "So you see, doctor, that cow, that was an antidepressant, 00:06:16.583 --> 00:06:18.050 that's what you mean, right?" NOTE Paragraph 00:06:18.074 --> 00:06:19.225 (Laughter) NOTE Paragraph 00:06:19.249 --> 00:06:22.302 (Applause) NOTE Paragraph 00:06:22.326 --> 00:06:25.199 If you'd been raised to think about depression the way I was, 00:06:25.223 --> 00:06:26.835 and most of the people here were, 00:06:26.859 --> 00:06:28.533 that sounds like a bad joke, right? 00:06:28.557 --> 00:06:30.581 "I went to my doctor for an antidepressant, 00:06:30.605 --> 00:06:31.771 she gave me a cow." 00:06:31.795 --> 00:06:34.822 But what those Cambodian doctors knew intuitively, 00:06:34.846 --> 00:06:37.823 based on this individual, unscientific anecdote, 00:06:37.847 --> 00:06:41.132 is what the leading medical body in the world, 00:06:41.156 --> 00:06:43.243 the World Health Organization, 00:06:43.267 --> 00:06:45.457 has been trying to tell us for years, 00:06:45.481 --> 00:06:47.973 based on the best scientific evidence. NOTE Paragraph 00:06:48.576 --> 00:06:50.505 If you're depressed, 00:06:50.529 --> 00:06:51.906 if you're anxious, 00:06:53.008 --> 00:06:56.268 you're not weak, you're not crazy, 00:06:56.292 --> 00:06:59.877 you're not, in the main, a machine with broken parts. 00:07:00.950 --> 00:07:03.484 You're a human being with unmet needs. 00:07:03.919 --> 00:07:07.459 And it's just as important to think here about what those Cambodian doctors 00:07:07.483 --> 00:07:09.800 and the World Health Organization are not saying. 00:07:09.824 --> 00:07:11.356 They did not say to this farmer, 00:07:11.380 --> 00:07:14.181 "Hey, buddy, you need to pull yourself together. 00:07:14.205 --> 00:07:17.472 It's your job to figure out and fix this problem on your own." 00:07:17.851 --> 00:07:19.843 On the contrary, what they said is, 00:07:19.867 --> 00:07:23.391 "We're here as a group to pull together with you, 00:07:23.415 --> 00:07:27.827 so together, we can figure out and fix this problem." 00:07:28.543 --> 00:07:32.559 This is what every depressed person needs, 00:07:32.583 --> 00:07:35.828 and it's what every depressed person deserves. NOTE Paragraph 00:07:35.852 --> 00:07:38.839 This is why one of the leading doctors at the United Nations, 00:07:38.863 --> 00:07:41.181 in their official statement for World Health Day, 00:07:41.205 --> 00:07:42.696 couple of years back in 2017, 00:07:42.720 --> 00:07:45.537 said we need to talk less about chemical imbalances 00:07:45.561 --> 00:07:48.618 and more about the imbalances in the way we live. 00:07:48.920 --> 00:07:50.893 Drugs give real relief to some people -- 00:07:50.917 --> 00:07:53.047 they gave relief to me for a while -- 00:07:53.071 --> 00:07:57.498 but precisely because this problem goes deeper than their biology, 00:07:57.522 --> 00:08:00.577 the solutions need to go much deeper, too. NOTE Paragraph 00:08:00.601 --> 00:08:03.188 But when I first learned that, 00:08:03.212 --> 00:08:04.895 I remember thinking, 00:08:04.919 --> 00:08:07.045 "OK, I could see all the scientific evidence, 00:08:07.069 --> 00:08:08.641 I read a huge number of studies, 00:08:08.665 --> 00:08:11.971 I interviewed a huge number of the experts who were explaining this," 00:08:11.995 --> 00:08:14.381 but I kept thinking, "How can we possibly do that?" 00:08:14.405 --> 00:08:16.318 The things that are making us depressed 00:08:16.342 --> 00:08:18.833 are in most cases more complex than what was going on 00:08:18.857 --> 00:08:20.154 with this Cambodian farmer. 00:08:20.178 --> 00:08:22.812 Where do we even begin with that insight? NOTE Paragraph 00:08:22.836 --> 00:08:26.085 But then, in the long journey for my book, 00:08:26.109 --> 00:08:27.680 all over the world, 00:08:27.704 --> 00:08:30.299 I kept meeting people who were doing exactly that, 00:08:30.323 --> 00:08:32.775 from Sydney, to San Francisco, 00:08:32.799 --> 00:08:33.971 to São Paulo. 00:08:33.995 --> 00:08:36.061 I kept meeting people who were understanding 00:08:36.085 --> 00:08:38.432 the deeper causes of depression and anxiety 00:08:38.456 --> 00:08:40.871 and, as groups, fixing them. 00:08:40.895 --> 00:08:43.576 Obviously, I can't tell you about all the amazing people 00:08:43.600 --> 00:08:45.076 I got to know and wrote about, 00:08:45.100 --> 00:08:48.553 or all of the nine causes of depression and anxiety that I learned about, 00:08:48.577 --> 00:08:51.059 because they won't let me give a 10-hour TED Talk -- 00:08:51.083 --> 00:08:52.835 you can complain about that to them. NOTE Paragraph 00:08:52.859 --> 00:08:54.789 But I want to focus on two of the causes 00:08:54.813 --> 00:08:58.226 and two of the solutions that emerge from them, if that's alright. 00:08:58.578 --> 00:08:59.728 Here's the first. 00:09:00.285 --> 00:09:03.293 We are the loneliest society in human history. 00:09:03.317 --> 00:09:06.150 There was a recent study that asked Americans, 00:09:06.174 --> 00:09:09.324 "Do you feel like you're no longer close to anyone?" 00:09:09.348 --> 00:09:12.999 And 39 percent of people said that described them. 00:09:13.023 --> 00:09:14.387 "No longer close to anyone." 00:09:14.411 --> 00:09:16.908 In the international measurements of loneliness, 00:09:16.932 --> 00:09:19.490 Britain and the rest of Europe are just behind the US, 00:09:19.514 --> 00:09:21.299 in case anyone here is feeling smug. NOTE Paragraph 00:09:21.323 --> 00:09:22.331 (Laughter) NOTE Paragraph 00:09:22.355 --> 00:09:24.244 I spent a lot of time discussing this 00:09:24.268 --> 00:09:26.664 with the leading expert in the world on loneliness, 00:09:26.688 --> 00:09:28.942 an incredible man named professor John Cacioppo, 00:09:28.966 --> 00:09:30.117 who was at Chicago, 00:09:30.141 --> 00:09:32.964 and I thought a lot about one question his work poses to us. 00:09:32.988 --> 00:09:35.293 Professor Cacioppo asked, 00:09:35.317 --> 00:09:36.967 "Why do we exist? 00:09:36.991 --> 00:09:38.944 Why are we here, why are we alive?" 00:09:38.968 --> 00:09:41.174 One key reason 00:09:41.198 --> 00:09:44.015 is that our ancestors on the savannas of Africa 00:09:44.039 --> 00:09:45.759 were really good at one thing. 00:09:46.287 --> 00:09:49.577 They weren't bigger than the animals they took down a lot of the time, 00:09:49.601 --> 00:09:52.914 they weren't faster than the animals they took down a lot of the time, 00:09:52.938 --> 00:09:55.652 but they were much better at banding together into groups 00:09:55.676 --> 00:09:57.276 and cooperating. 00:09:57.300 --> 00:09:59.561 This was our superpower as a species -- 00:09:59.585 --> 00:10:00.990 we band together, 00:10:01.014 --> 00:10:03.490 just like bees evolved to live in a hive, 00:10:03.514 --> 00:10:05.746 humans evolved to live in a tribe. 00:10:05.770 --> 00:10:09.580 And we are the first humans ever 00:10:10.492 --> 00:10:11.959 to disband our tribes. 00:10:12.484 --> 00:10:14.551 And it is making us feel awful. 00:10:15.048 --> 00:10:17.192 But it doesn't have to be this way. NOTE Paragraph 00:10:17.216 --> 00:10:19.850 One of the heroes in my book, and in fact, in my life, 00:10:19.874 --> 00:10:21.969 is a doctor named Sam Everington. 00:10:21.993 --> 00:10:24.731 He's a general practitioner in a poor part of East London, 00:10:24.755 --> 00:10:26.334 where I lived for many years. 00:10:26.358 --> 00:10:28.045 And Sam was really uncomfortable, 00:10:28.069 --> 00:10:29.625 because he had loads of patients 00:10:29.649 --> 00:10:32.093 coming to him with terrible depression and anxiety. 00:10:32.117 --> 00:10:34.839 And like me, he's not opposed to chemical antidepressants, 00:10:34.863 --> 00:10:37.085 he thinks they give some relief to some people. 00:10:37.109 --> 00:10:38.482 But he could see two things. 00:10:38.506 --> 00:10:42.061 Firstly, his patients were depressed and anxious a lot of the time 00:10:42.085 --> 00:10:45.823 for totally understandable reasons, like loneliness. 00:10:45.847 --> 00:10:49.291 And secondly, although the drugs were giving some relief to some people, 00:10:49.315 --> 00:10:51.583 for many people, they didn't solve the problem. 00:10:51.607 --> 00:10:53.140 The underlying problem. 00:10:53.871 --> 00:10:56.522 One day, Sam decided to pioneer a different approach. 00:10:56.546 --> 00:10:58.998 A woman came to his center, his medical center, 00:10:59.022 --> 00:11:00.489 called Lisa Cunningham. 00:11:00.513 --> 00:11:02.387 I got to know Lisa later. 00:11:02.411 --> 00:11:06.495 And Lisa had been shut away in her home with crippling depression and anxiety 00:11:06.519 --> 00:11:07.669 for seven years. 00:11:08.898 --> 00:11:11.823 And when she came to Sam's center, she was told, "Don't worry, 00:11:11.847 --> 00:11:13.677 we'll carry on giving you these drugs, 00:11:13.701 --> 00:11:16.498 but we're also going to prescribe something else. 00:11:16.522 --> 00:11:19.965 We're going to prescribe for you to come here to this center twice a week 00:11:19.989 --> 00:11:22.767 to meet with a group of other depressed and anxious people, 00:11:22.791 --> 00:11:25.601 not to talk about how miserable you are, 00:11:25.625 --> 00:11:29.172 but to figure out something meaningful you can all do together 00:11:29.196 --> 00:11:32.299 so you won't be lonely and you won't feel like life is pointless." NOTE Paragraph 00:11:32.323 --> 00:11:35.098 The first time this group met, 00:11:35.122 --> 00:11:37.378 Lisa literally started vomiting with anxiety, 00:11:37.402 --> 00:11:39.323 it was so overwhelming for her. 00:11:39.347 --> 00:11:41.981 But people rubbed her back, the group started talking, 00:11:42.005 --> 00:11:43.680 they were like, "What could we do?" 00:11:43.704 --> 00:11:45.998 These are inner-city, East London people like me, 00:11:46.022 --> 00:11:48.070 they didn't know anything about gardening. 00:11:48.094 --> 00:11:50.339 They were like, "Why don't we learn gardening?" 00:11:50.363 --> 00:11:52.529 There was an area behind the doctors' offices 00:11:52.553 --> 00:11:53.704 that was just scrubland. 00:11:53.728 --> 00:11:55.610 "Why don't we make this into a garden?" 00:11:55.634 --> 00:11:57.809 They started to take books out of the library, 00:11:57.833 --> 00:11:59.318 started to watch YouTube clips. 00:11:59.342 --> 00:12:01.501 They started to get their fingers in the soil. 00:12:01.844 --> 00:12:04.887 They started to learn the rhythms of the seasons. 00:12:04.911 --> 00:12:06.241 There's a lot of evidence 00:12:06.265 --> 00:12:07.894 that exposure to the natural world 00:12:07.918 --> 00:12:09.894 is a really powerful antidepressant. 00:12:09.918 --> 00:12:12.927 But they started to do something even more important. 00:12:13.347 --> 00:12:15.377 They started to form a tribe. 00:12:15.401 --> 00:12:17.212 They started to form a group. 00:12:17.236 --> 00:12:19.260 They started to care about each other. 00:12:19.284 --> 00:12:20.958 If one of them didn't show up, 00:12:20.982 --> 00:12:23.502 the others would go looking for them -- "Are you OK?" 00:12:23.526 --> 00:12:26.137 Help them figure out what was troubling them that day. 00:12:26.161 --> 00:12:27.964 The way Lisa put it to me, 00:12:27.988 --> 00:12:30.585 "As the garden began to bloom, 00:12:30.609 --> 00:12:31.876 we began to bloom." NOTE Paragraph 00:12:32.474 --> 00:12:34.506 This approach is called social prescribing, 00:12:34.530 --> 00:12:36.045 it's spreading all over Europe. 00:12:36.069 --> 00:12:38.370 And there's a small, but growing body of evidence 00:12:38.394 --> 00:12:41.274 suggesting it can produce real and meaningful falls 00:12:41.298 --> 00:12:43.276 in depression and anxiety. NOTE Paragraph 00:12:43.300 --> 00:12:47.021 And one day, I remember standing in the garden 00:12:47.045 --> 00:12:49.526 that Lisa and her once-depressed friends had built -- 00:12:49.550 --> 00:12:51.134 it's a really beautiful garden -- 00:12:51.158 --> 00:12:52.349 and having this thought, 00:12:52.373 --> 00:12:56.244 it's very much inspired by a guy called professor Hugh Mackay in Australia. 00:12:56.268 --> 00:13:00.649 I was thinking, so often when people feel down in this culture, 00:13:00.673 --> 00:13:03.737 what we say to them -- I'm sure everyone here said it, I have -- 00:13:03.761 --> 00:13:06.985 we say, "You just need to be you, be yourself." 00:13:07.742 --> 00:13:10.692 And I've realized, actually, what we should say to people is, 00:13:10.716 --> 00:13:11.866 "Don't be you. 00:13:12.306 --> 00:13:13.639 Don't be yourself. 00:13:14.218 --> 00:13:16.427 Be us, be we. 00:13:16.765 --> 00:13:18.090 Be part of a group." NOTE Paragraph 00:13:18.114 --> 00:13:21.820 (Applause) NOTE Paragraph 00:13:21.844 --> 00:13:24.423 The solution to these problems 00:13:24.447 --> 00:13:27.598 does not lie in drawing more and more on your resources 00:13:27.622 --> 00:13:29.061 as an isolated individual -- 00:13:29.085 --> 00:13:31.125 that's partly what got us in this crisis. 00:13:31.149 --> 00:13:33.902 It lies on reconnecting with something bigger than you. NOTE Paragraph 00:13:33.926 --> 00:13:36.347 And that really connects to one of the other causes 00:13:36.371 --> 00:13:39.268 of depression and anxiety that I wanted to talk to you about. 00:13:39.292 --> 00:13:40.982 So everyone knows 00:13:41.006 --> 00:13:44.752 junk food has taken over our diets and made us physically sick. 00:13:44.776 --> 00:13:46.982 I don't say that with any sense of superiority, 00:13:47.006 --> 00:13:49.405 I literally came to give this talk from McDonald's. 00:13:49.429 --> 00:13:52.942 I saw all of you eating that healthy TED breakfast, I was like no way. 00:13:52.966 --> 00:13:58.109 But just like junk food has taken over our diets and made us physically sick, 00:13:58.133 --> 00:14:02.243 a kind of junk values have taken over our minds 00:14:02.267 --> 00:14:03.745 and made us mentally sick. 00:14:04.157 --> 00:14:07.261 For thousands of years, philosophers have said, 00:14:07.285 --> 00:14:11.873 if you think life is about money, and status and showing off, 00:14:11.897 --> 00:14:13.420 you're going to feel like crap. 00:14:13.444 --> 00:14:15.511 That's not an exact quote from Schopenhauer, 00:14:15.535 --> 00:14:17.307 but that is the gist of what he said. NOTE Paragraph 00:14:17.331 --> 00:14:20.357 But weirdly, hardy anyone had scientifically investigated this, 00:14:20.381 --> 00:14:24.030 until a truly extraordinary person I got to know, named professor Tim Kasser, 00:14:24.054 --> 00:14:26.347 who's at Knox College in Illinois, 00:14:26.371 --> 00:14:28.934 and he's been researching this for about 30 years now. 00:14:28.958 --> 00:14:31.974 And his research suggests several really important things. 00:14:31.998 --> 00:14:35.189 Firstly, the more you believe 00:14:35.213 --> 00:14:39.578 you can buy and display your way out of sadness, 00:14:39.602 --> 00:14:41.793 and into a good life, 00:14:41.817 --> 00:14:44.729 the more likely you are to become depressed and anxious. 00:14:44.753 --> 00:14:46.046 And secondly, 00:14:46.070 --> 00:14:50.658 as a society, we have become much more driven by these beliefs. 00:14:50.682 --> 00:14:52.095 All throughout my lifetime, 00:14:52.119 --> 00:14:56.312 under the weight of advertising and Instagram and everything like them. NOTE Paragraph 00:14:56.871 --> 00:14:58.244 And as I thought about this, 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. 00:15:04.053 --> 00:15:07.926 We've been trained to look for happiness in all the wrong places, 00:15:07.950 --> 00:15:10.720 and just like junk food doesn't meet your nutritional needs 00:15:10.744 --> 00:15:13.042 and actually makes you feel terrible, 00:15:13.066 --> 00:15:16.208 junk values don't meet your psychological needs, 00:15:16.232 --> 00:15:18.874 and they take you away from a good life. 00:15:18.898 --> 00:15:21.521 But when I first spent time with professor Kasser 00:15:21.545 --> 00:15:23.022 and I was learning all this, 00:15:23.046 --> 00:15:25.633 I felt a really weird mixture of emotions. 00:15:25.657 --> 00:15:28.347 Because on the one hand, I found this really challenging. 00:15:28.371 --> 00:15:31.633 I could see how often in my own life, when I felt down, 00:15:31.657 --> 00:15:36.922 I tried to remedy it with some kind of show-offy, grand external solution. 00:15:37.441 --> 00:15:40.131 And I could see why that did not work well for me. 00:15:40.930 --> 00:15:43.812 I also thought, isn't this kind of obvious? 00:15:43.836 --> 00:15:45.581 Isn't this almost like banal, right? 00:15:45.605 --> 00:15:46.930 If I said to everyone here, 00:15:46.954 --> 00:15:49.097 none of you are going to lie on your deathbed 00:15:49.121 --> 00:15:52.437 and think about all the shoes you bought and all the retweets you got, 00:15:52.461 --> 00:15:54.144 you're going to think about moments 00:15:54.168 --> 00:15:56.279 of love, meaning and connection in your life. 00:15:56.303 --> 00:15:58.248 I think that seems almost like a cliché. 00:15:58.272 --> 00:16:00.621 But I kept talking to professor Kasser and saying, 00:16:00.645 --> 00:16:02.998 "Why am I feeling this strange doubleness?" 00:16:03.022 --> 00:16:06.829 And he said, "At some level, we all know these things. 00:16:06.853 --> 00:16:09.228 But in this culture, we don't live by them." 00:16:09.252 --> 00:16:11.331 We know them so well they've become clichés, 00:16:11.355 --> 00:16:12.633 but we don't live by them. 00:16:12.657 --> 00:16:15.866 I kept asking why, why would we know something so profound, 00:16:15.890 --> 00:16:17.176 but not live by it? 00:16:17.200 --> 00:16:20.604 And after a while, professor Kasser said to me, 00:16:20.628 --> 00:16:23.049 "Because we live in a machine 00:16:23.073 --> 00:16:26.806 that is designed to get us to neglect what is important about life." 00:16:27.260 --> 00:16:28.847 I had to really think about that. 00:16:28.871 --> 00:16:30.276 "Because we live in a machine 00:16:30.300 --> 00:16:33.978 that is designed to get us to neglect what is important about life." NOTE Paragraph 00:16:34.299 --> 00:16:38.077 And professor Kasser wanted to figure out if we can disrupt that machine. 00:16:38.101 --> 00:16:39.974 He's done loads of research into this; 00:16:39.998 --> 00:16:41.553 I'll tell you about one example, 00:16:41.577 --> 00:16:45.077 and I really urge everyone here to try this with their friends and family. 00:16:45.101 --> 00:16:48.443 With a guy called Nathan Dungan, he got a group of teenagers and adults 00:16:48.467 --> 00:16:52.680 to come together for a series of sessions over a period of time, to meet up. 00:16:52.704 --> 00:16:54.467 And part of the point of the group 00:16:54.491 --> 00:16:57.791 was to get people to think about a moment in their life 00:16:57.815 --> 00:17:00.561 they had actually found meaning and purpose. 00:17:00.585 --> 00:17:02.728 For different people, it was different things. 00:17:02.752 --> 00:17:06.369 For some people, it was playing music, writing, helping someone -- 00:17:06.393 --> 00:17:09.196 I'm sure everyone here can picture something, right? 00:17:09.220 --> 00:17:12.101 And part of the point of the group was to get people to ask, 00:17:12.125 --> 00:17:14.887 "OK, how could you dedicate more of your life 00:17:14.911 --> 00:17:17.595 to pursuing these moments of meaning and purpose, 00:17:17.619 --> 00:17:20.569 and less to, I don't know, buying crap you don't need, 00:17:20.593 --> 00:17:23.315 putting it on social media and trying to get people to go, 00:17:23.339 --> 00:17:24.606 'OMG, so jealous!'" NOTE Paragraph 00:17:24.958 --> 00:17:26.601 And what they found was, 00:17:26.625 --> 00:17:27.959 just having these meetings, 00:17:27.983 --> 00:17:31.093 it was like a kind of Alcoholics Anonymous for consumerism, right? 00:17:31.807 --> 00:17:34.760 Getting people to have these meetings, articulate these values, 00:17:34.784 --> 00:17:37.315 determine to act on them and check in with each other, 00:17:37.339 --> 00:17:40.196 led to a marked shift in people's values. 00:17:40.220 --> 00:17:44.633 It took them away from this hurricane of depression-generating messages 00:17:44.657 --> 00:17:47.291 training us to seek happiness in the wrong places, 00:17:47.315 --> 00:17:50.656 and towards more meaningful and nourishing values 00:17:50.680 --> 00:17:52.680 that lift us out of depression. NOTE Paragraph 00:17:53.347 --> 00:17:56.649 But with all the solutions that I saw and have written about, 00:17:56.673 --> 00:17:59.412 and many I can't talk about here, 00:17:59.436 --> 00:18:00.807 I kept thinking, 00:18:00.831 --> 00:18:04.530 you know: Why did it take me so long to see these insights? 00:18:04.554 --> 00:18:06.570 Because when you explain them to people -- 00:18:06.594 --> 00:18:09.038 some of them are more complicated, but not all -- 00:18:09.062 --> 00:18:12.306 when you explain this to people, it's not like rocket science, right? 00:18:12.330 --> 00:18:14.425 At some level, we already know these things. 00:18:14.449 --> 00:18:17.086 Why do we find it so hard to understand? 00:18:17.110 --> 00:18:19.044 I think there's many reasons. 00:18:19.475 --> 00:18:23.744 But I think one reason is that we have to change our understanding 00:18:23.768 --> 00:18:27.188 of what depression and anxiety actually are. 00:18:27.776 --> 00:18:29.958 There are very real biological contributions 00:18:29.982 --> 00:18:31.715 to depression and anxiety. 00:18:32.117 --> 00:18:35.871 But if we allow the biology to become the whole picture, 00:18:35.895 --> 00:18:37.141 as I did for so long, 00:18:37.165 --> 00:18:41.230 as I would argue our culture has done pretty much most of my life, 00:18:41.254 --> 00:18:45.111 what we're implicitly saying to people is, and this isn't anyone's intention, 00:18:45.135 --> 00:18:48.172 but what we're implicitly saying to people is, 00:18:48.196 --> 00:18:50.498 "Your pain doesn't mean anything. 00:18:50.522 --> 00:18:51.958 It's just a malfunction. 00:18:51.982 --> 00:18:54.451 It's like a glitch in a computer program, 00:18:54.475 --> 00:18:57.142 it's just a wiring problem in your head." 00:18:58.061 --> 00:19:01.168 But I was only able to start changing my life 00:19:01.192 --> 00:19:05.257 when I realized your depression is not a malfunction. 00:19:06.620 --> 00:19:07.770 It's a signal. 00:19:08.684 --> 00:19:10.691 Your depression is a signal. 00:19:11.077 --> 00:19:12.918 It's telling you something. NOTE Paragraph 00:19:12.942 --> 00:19:17.553 (Applause) NOTE Paragraph 00:19:17.577 --> 00:19:19.966 We feel this way for reasons, 00:19:19.990 --> 00:19:22.705 and they can be hard to see in the throes of depression -- 00:19:22.729 --> 00:19:25.339 I understand that really well from personal experience. 00:19:25.363 --> 00:19:28.846 But with the right help, we can understand these problems 00:19:28.870 --> 00:19:31.344 and we can fix these problems together. 00:19:31.368 --> 00:19:32.560 But to do that, 00:19:32.584 --> 00:19:34.322 the very first step 00:19:34.346 --> 00:19:36.964 is we have to stop insulting these signals 00:19:36.988 --> 00:19:41.180 by saying they're a sign of weakness, or madness or purely biological, 00:19:41.204 --> 00:19:43.139 except for a tiny number of people. 00:19:43.163 --> 00:19:46.789 We need to start listening to these signals, 00:19:46.813 --> 00:19:50.085 because they're telling us something we really need to hear. 00:19:50.514 --> 00:19:55.537 It's only when we truly listen to these signals, 00:19:55.561 --> 00:19:59.576 and we honor these signals and respect these signals, 00:19:59.600 --> 00:20:01.847 that we're going to begin to see 00:20:01.871 --> 00:20:06.029 the liberating, nourishing, deeper solutions. 00:20:07.133 --> 00:20:11.206 The cows that are waiting all around us.
