WEBVTT 00:00:15.650 --> 00:00:19.750 We have worked very hard to achieve living longer 00:00:20.120 --> 00:00:25.310 and yet today we consider aging as a problem. 00:00:26.420 --> 00:00:30.579 I also used to consider population aging as a problem, 00:00:31.219 --> 00:00:33.789 that's why some years ago I packed, left everything behind 00:00:33.930 --> 00:00:37.640 and enroled a top university in the USA, Johns Hopkins University, 00:00:37.640 --> 00:00:41.570 to acquire tools that'd help me to fight the aging challenge. 00:00:43.320 --> 00:00:47.710 What I was not expecting was to realize that my initial vision, 00:00:48.350 --> 00:00:51.650 my perspective on aging, was distorted. 00:00:53.040 --> 00:00:57.390 I had a series of beliefs, stereotypes and prejudices 00:00:57.880 --> 00:00:59.930 that prevented me from seeing clearly. 00:01:00.750 --> 00:01:04.410 We can think of aging either as positive or as negative 00:01:05.349 --> 00:01:07.480 but we all share one thing: 00:01:07.480 --> 00:01:10.150 That idea is conformed very early in our lives. 00:01:10.460 --> 00:01:12.710 Studies in the '70s 00:01:12.710 --> 00:01:15.609 conducted interviews on 4 to 11 year-old children, 00:01:16.029 --> 00:01:19.279 a gerontologist, Seefeldt, and others 00:01:19.569 --> 00:01:23.290 asked children about their perception of the elderly. 00:01:25.229 --> 00:01:28.580 Results are horrifying. 00:01:29.510 --> 00:01:34.270 Two out of three children believed that older people 00:01:34.620 --> 00:01:39.230 were helpess, unable to take care for themselves, 00:01:39.990 --> 00:01:42.160 and generally passive. 00:01:43.780 --> 00:01:46.910 And that negative perception they had about aging 00:01:47.200 --> 00:01:50.810 would also become an expectation of their own aging. 00:01:51.270 --> 00:01:53.579 60 percent of those children 00:01:54.479 --> 00:01:58.949 already predicted that when they'd be old, they were going to feel awful. 00:02:00.729 --> 00:02:05.690 And how can any 4, 5 or 6 year old know how'd they feel when elderly? 00:02:06.730 --> 00:02:09.299 Probably, what goes on there is that we are absorbing 00:02:09.299 --> 00:02:12.130 that stereotype and that belief from our environment. 00:02:13.470 --> 00:02:16.670 Actually, in the Western world, Europe and North America, 00:02:16.670 --> 00:02:19.690 there's generally a very negative perception of old age, 00:02:20.030 --> 00:02:23.410 it's what we call "ageism" or discrimination by age. 00:02:24.320 --> 00:02:26.670 And what happens when those children grow up? 00:02:26.850 --> 00:02:29.280 By then the stereotype is reinforced, 00:02:29.280 --> 00:02:30.950 the belief is replayed 00:02:30.950 --> 00:02:35.400 by the mass media, advertising, movies -- 00:02:35.920 --> 00:02:39.240 If you give a closer look, how is aging usually portrayed? 00:02:39.240 --> 00:02:40.930 Generally not positive. 00:02:41.720 --> 00:02:47.160 At most it's warm, but never as an active aging. 00:02:47.650 --> 00:02:51.000 Actually, in the 90s another very interesting experiment 00:02:51.020 --> 00:02:53.750 was conducted by Burke on healthcare professionals. 00:02:54.300 --> 00:02:57.750 He wanted to analyze why some health professionals 00:02:57.750 --> 00:03:00.780 would talk to older people as if they were children, 00:03:01.140 --> 00:03:03.920 we call this the "elder talk", 00:03:03.920 --> 00:03:06.260 probably most of you have done it or at least have seen it: 00:03:06.810 --> 00:03:10.690 "Hi Carmencita, how are you today? 00:03:11.000 --> 00:03:15.480 Here is your little pill for the heart". 00:03:16.760 --> 00:03:22.110 Right? And Carmen is 75 years old, a professor emeritus at university 00:03:22.250 --> 00:03:26.199 and she is in perfect cognitive state. (Laughter) 00:03:27.479 --> 00:03:29.760 Burke proved that healthcare professionals 00:03:29.760 --> 00:03:31.730 would speak like this to the elderly 00:03:31.890 --> 00:03:34.990 regardless of their cognitive state, 00:03:35.240 --> 00:03:38.510 based only on their own beliefs about old age. 00:03:39.390 --> 00:03:43.640 I invite you to never talk like this to an older person. 00:03:44.840 --> 00:03:48.570 (Applause) 00:03:53.470 --> 00:03:56.610 In 2008 an article in The New York Times 00:03:57.420 --> 00:04:00.070 gathered all the scientific evidence 00:04:00.070 --> 00:04:02.470 of why talking like that to older people 00:04:02.470 --> 00:04:04.620 is harmful to their health. 00:04:04.990 --> 00:04:08.310 In a very simple way we can realize we are reinforcing their idea 00:04:08.310 --> 00:04:10.840 that they are useless and incapable. 00:04:11.510 --> 00:04:14.090 No, the elderly are not like children. 00:04:15.120 --> 00:04:18.190 In another very interesting study also starting in the 70s 00:04:18.190 --> 00:04:21.829 a gerontologist, Ashley, went to a town in Ohio 00:04:21.829 --> 00:04:25.740 and managed to convince 2/3 of the population over 50 00:04:25.750 --> 00:04:27.720 of participating in it. 00:04:28.050 --> 00:04:30.090 That's an achievement for any researcher 00:04:30.090 --> 00:04:32.839 because nobody wants to take part in scientific studies, 00:04:32.839 --> 00:04:34.720 less if they are periodic. 00:04:34.990 --> 00:04:37.560 These people were periodically asked 00:04:37.560 --> 00:04:40.630 about their mental health status, their physical health status, 00:04:40.630 --> 00:04:43.600 their working environment, family, etc. 00:04:44.080 --> 00:04:47.640 And they were also asked some questions on their perception of old age: 00:04:48.490 --> 00:04:51.650 Do you think you become less happy as you get older? 00:04:53.680 --> 00:04:56.420 Do you think that as you get older you are less useful? 00:04:58.180 --> 00:05:00.230 Well, this study was very interesting, 00:05:00.480 --> 00:05:03.300 and had the most powerful results 15 years later. 00:05:04.050 --> 00:05:08.130 A social psychologist, Becca Levy, from Yale University, 00:05:08.300 --> 00:05:12.130 has revolutionized the world -- at least for me, my world -- 00:05:12.130 --> 00:05:14.970 by proving that the negative stereotype of old age 00:05:14.970 --> 00:05:17.520 becomes a self-fulfilling prophecy. 00:05:18.070 --> 00:05:20.410 Meaning that it affects our health, 00:05:20.410 --> 00:05:23.870 if we think we are going to age badly, we most probably will. 00:05:24.190 --> 00:05:28.090 Becca Levy with her Ohio study resolved to test an hypothesis: 00:05:28.090 --> 00:05:31.870 do people with a positive vision of old age live longer? 00:05:32.550 --> 00:05:35.840 She went to Ohio and retrieved all the death certificates 00:05:35.880 --> 00:05:38.249 from people participating on the research who had already died 00:05:38.249 --> 00:05:41.810 and compared the life expectancy of people with a positive vision 00:05:42.290 --> 00:05:45.039 with those who had a negative vision of old age. 00:05:45.429 --> 00:05:49.410 And she found that those with a positive vision lived longer. 00:05:51.700 --> 00:05:54.520 How much longer do you think they lived? 00:05:55.700 --> 00:05:59.729 One year? Two years? 00:06:01.279 --> 00:06:04.419 It's 7.6 years! 00:06:05.919 --> 00:06:09.130 That is 7.6 years more of life expectancy 00:06:09.130 --> 00:06:12.509 in those with a positive vision of old age. 00:06:12.759 --> 00:06:14.889 Monitoring all other factors. 00:06:15.149 --> 00:06:17.069 Do you know how much it costs as society 00:06:17.069 --> 00:06:20.029 to increase life expectancy ... in 3 months? 00:06:20.349 --> 00:06:23.280 "With surgery ... got another year of life expectancy ..." 00:06:24.390 --> 00:06:26.659 Changing our attitude. 00:06:28.210 --> 00:06:30.930 A change in our beliefs about aging. 00:06:31.530 --> 00:06:35.279 And how can a belief become a change in your cells, 00:06:35.279 --> 00:06:37.169 in your life expectancy? 00:06:37.639 --> 00:06:39.269 It's very revolutionary. 00:06:40.529 --> 00:06:42.409 Well, they've managed to understand 00:06:42.409 --> 00:06:46.309 how the negative stereotype is associated to things like memory, 00:06:46.819 --> 00:06:49.439 to our performance in cognitive tests. 00:06:50.229 --> 00:06:54.670 In 2013, they managed to associate the negative vision of old age 00:06:54.670 --> 00:06:57.469 with the size of our hippocampus. 00:06:57.469 --> 00:07:01.389 So, our ideas change the anatomy of our brain. 00:07:03.860 --> 00:07:06.170 And to apply it a little in our day to day 00:07:06.170 --> 00:07:08.240 there are many hypotheses of how this happens, 00:07:08.240 --> 00:07:11.689 what is the biological mechanism, how does this happen? 00:07:11.689 --> 00:07:14.609 But there's one thing that we have all said or listened, 00:07:14.819 --> 00:07:18.359 that is: "Me, at my age..." 00:07:19.899 --> 00:07:23.489 "What am I doing wearing sneakers at my age?" 00:07:24.189 --> 00:07:26.499 "What am I doing in the gym at my age?" 00:07:26.889 --> 00:07:29.350 "What am I doing, being 40, with those who are 20?" 00:07:29.660 --> 00:07:32.960 Suddenly, we stop doing things that are good for our health 00:07:33.250 --> 00:07:35.429 because there's some kind of expiration date 00:07:35.459 --> 00:07:37.799 from which we throw in the towel. 00:07:38.449 --> 00:07:41.479 It seems like the day we turn 65, 00:07:41.929 --> 00:07:44.589 "game over", we are done, 00:07:44.779 --> 00:07:48.109 we can no longer introduce any positive activity for our health 00:07:48.109 --> 00:07:50.039 because it's not worth it, there's no turning back, 00:07:50.039 --> 00:07:53.750 aging is negative by definition, it is inexorable. 00:07:56.800 --> 00:08:00.360 Actually that number, 65 years, 00:08:00.610 --> 00:08:03.679 I tried to find out where it came from, 00:08:04.789 --> 00:08:08.829 and the most probable cause is called Otto Von Bismarck, 00:08:10.379 --> 00:08:13.729 who was the German Chancellor in the late 1800s. 00:08:14.200 --> 00:08:19.000 In 1893 he introduced the world's first retirement policy. 00:08:19.400 --> 00:08:21.360 The right to retirement is very recent, 00:08:21.360 --> 00:08:24.370 the workers were protesting a lot 00:08:24.370 --> 00:08:26.320 and he wanted to calm things down a bit, 00:08:26.320 --> 00:08:29.030 so he stablished the retirement age in 70 years. 00:08:29.650 --> 00:08:32.400 When I researched a little 00:08:32.400 --> 00:08:36.009 about which was the life expectancy in Germany in 1893 -- 00:08:36.720 --> 00:08:39.600 (Laughter) 00:08:40.440 --> 00:08:43.938 How long do you think people lived in 1893? 00:08:44.530 --> 00:08:47.930 Life expectancy at birth was 39 years old. (Laughter) 00:08:49.160 --> 00:08:53.030 Otto Von Bismarck was a genius -- (Laughter) 00:08:54.550 --> 00:08:57.590 Those who were lucky and managed to reach 30, 00:08:57.590 --> 00:09:01.440 would live on average another 30 years, that is, 60. 00:09:02.170 --> 00:09:04.880 Otto Von Bismarck lived up to 78, more or less, 00:09:04.880 --> 00:09:07.330 good for him, but not for the rest. (Laughter) 00:09:07.550 --> 00:09:11.680 Can you see there's no ground for this? There is no medical basis for 65. 00:09:12.580 --> 00:09:15.730 The other countries acquired that number, 70, 60 -- 00:09:15.920 --> 00:09:19.120 actually, in the United States it's said that 65 was adopted 00:09:19.120 --> 00:09:22.150 because someone said "60", another said "70", 00:09:22.150 --> 00:09:26.080 and a third said "let's not argue: 65". 00:09:27.110 --> 00:09:31.830 And now in the collective mind it has become some kind of halfway point 00:09:31.830 --> 00:09:38.680 in which we go deep into not having a solution nor remedy, 00:09:38.780 --> 00:09:40.650 and we do have a remedy. 00:09:41.140 --> 00:09:47.930 There are changes in our lifestyle that'd benefit us no matter when, 00:09:48.580 --> 00:09:54.630 for example, if after this talk you resolve to quit smoking, 00:09:57.800 --> 00:10:01.280 tomorrow, in 24 hours, your cardiovascular risk 00:10:01.280 --> 00:10:05.260 would have decreased, regardless of your age: 00:10:05.550 --> 00:10:08.170 20, 40, 60, 80... 00:10:09.680 --> 00:10:12.510 In two days, you'd recover your senses of smell and taste. 00:10:13.600 --> 00:10:17.490 Reducing our overweight, that constant struggle, 00:10:18.000 --> 00:10:19.980 at any time of our life, 00:10:19.980 --> 00:10:22.410 even if we are 80 years old, 00:10:22.410 --> 00:10:26.180 reducing overweight is positive, especially abdominal fat, 00:10:26.180 --> 00:10:31.499 the belly, which is a very important predictor of cardiovascular events, 00:10:31.709 --> 00:10:34.370 I'm sorry to break it to you. (Laughter) 00:10:35.910 --> 00:10:39.029 And let's point out not only the most physical things 00:10:39.029 --> 00:10:42.059 but also the cognitive and social, 00:10:42.319 --> 00:10:44.629 how about signing up to do something new, 00:10:44.629 --> 00:10:48.509 enroll a course, meet new people. 00:10:49.179 --> 00:10:51.469 The social environment, the people we meet 00:10:51.469 --> 00:10:55.089 is also essential in our aging, in our life in general. 00:10:55.569 --> 00:10:57.589 When I started researching, 00:10:57.589 --> 00:11:01.859 my goal was to find preventive medicine interventions 00:11:02.099 --> 00:11:07.799 that could improve the quality of life and life expectancy of older people, 00:11:07.999 --> 00:11:10.249 not only consider prevention in children, 00:11:10.249 --> 00:11:11.879 but also in older people. 00:11:12.109 --> 00:11:14.760 And I, as a doctor, thought about the classic issues: 00:11:14.760 --> 00:11:19.109 overweight, tobacco, excessive alcohol, sedentary lifestyle -- 00:11:19.889 --> 00:11:22.230 However, as I was researching, 00:11:22.230 --> 00:11:26.900 I had a US database which is representative of the whole country, 00:11:26.939 --> 00:11:29.889 its results are very solid, 00:11:30.149 --> 00:11:32.519 and people over 65 00:11:32.529 --> 00:11:34.689 were asked three questions about their neighborhood: 00:11:35.199 --> 00:11:38.960 Do you think that your neighbors know each other well? 00:11:40.250 --> 00:11:43.830 Do you think that those neighbors are willing to help each other? 00:11:44.149 --> 00:11:46.979 Can you trust your neighbors? 00:11:47.299 --> 00:11:49.409 It's a measure of social cohesion 00:11:49.409 --> 00:11:51.669 that sociologists used for other areas, 00:11:51.669 --> 00:11:53.339 not for preventive medicine. 00:11:53.539 --> 00:11:56.469 But it caught my attention and I included it in my models. 00:11:57.139 --> 00:12:00.259 And it turns out that people who had a high social cohesion, 00:12:00.549 --> 00:12:04.869 feeling that in their neighborhood people knew, helped and trusted each other, 00:12:04.869 --> 00:12:09.198 they have a 40 percent lower risk of suffering a cardiovascular event. 00:12:11.039 --> 00:12:13.129 Besides the classic risk factors, 00:12:13.129 --> 00:12:15.309 there's also the social risk factors, 00:12:15.309 --> 00:12:18.780 and our neighborhood, our environment, is very important for our health. 00:12:19.539 --> 00:12:23.720 Your neighbors affect your health.
