00:00 Aging is an inevitable process.
00:02 Our memory begins to deteriorate and our consciousness becomes confused.
00:07 We can no longer think quickly.
00:09 Our body is covered with pronounced wrinkles,
00:11 the skin loosens and the bones with the joints become fragile and painful.
00:15 And all this is impossible to repair, isn't it?
00:18 Well, not quite.
00:20 An old lady enters the kitchen, swallows some pills,
00:23 and a few hours later, she feels perfectly well.
00:26 Her consciousness awakens and her memories become clearer.
00:29 Thoughts flow faster and her mood improves.
00:33 This woman feels a boost of strength and her body is rejuvenated.
00:37 The wrinkles fade, the vision becomes clearer,
00:40 the spine straightens, the muscles get back in shape,
00:43 and the gray hair becomes dark again.
00:46 She looks in the mirror and realizes that she looks like the young girl she was decades ago.
00:51 And above all, she is not a character from a science fiction movie.
00:55 The technologies for the rejuvenation of the body already exist.
00:59 We are just at a preliminary stage of development.
01:01 And you can have enough time and money to wait and one day acquire this technology.
01:06 Today, scientists can already rejuvenate redheads.
01:11 At Harvard Medical School, scientists worked with old mice.
01:15 The cells in their eyes have been renewed and they have regained their ability to see clearly.
01:20 And if it is possible with the eyes, then everything else can also be rejuvenated.
01:25 Researchers have managed to do this by injecting a young mouse's blood.
01:30 Research and experiments in this field have shown that we do not properly conceive aging.
01:35 Our bodies have a copy of the "save" of our youth,
01:39 which means that the old cells retain the memory of their young state.
01:43 Scientists hope to one day activate this "save" and reverse aging.
01:48 The epigenome helps scientists understand this complex problem.
01:52 This mechanism determines which genes are activated and which genes are deactivated in our body.
01:57 We mean genes that are responsible for our health, the condition of our cells and that of our tissues.
02:03 Unfortunately, the older we get, the less the epigenome works well.
02:07 For example, it can activate genes that trigger certain diseases
02:11 and deactivate genes that protect the body from self-destruction.
02:14 This dysfunction in the epigenome is one of the causes of aging.
02:18 The functioning of this mechanism depends on the environment,
02:22 our habits, our sleep rhythm and our diet.
02:26 Theoretically, if the epigenome is stabilized, it begins to improve our genes again.
02:32 It is a hard task and it will take years before scientists can obtain exploitable results.
02:39 Such experiments inspire researchers and many people who would like to stop aging.
02:45 The bad news is that you may have to wait too long.
02:49 The good news is that you can slow down your aging without expensive technology.
02:54 A balanced diet, exercise, good sleep and vitamins can significantly slow down aging.
03:01 And now imagine that this drug appears in luxury clinics.
03:05 The richest people start buying it and then something goes wrong.
03:09 Businessmen, stars and inventors of all kinds reverse aging.
03:14 But they cannot stop the process.
03:17 That is to say that the cells of the body stop aging.
03:20 But they also continue to return to a younger state.
03:23 While ordinary people die of old age, billionaires reach the end of their young lives.
03:29 But the strangest thing is that the descendants of these people are born with the same particularity.
03:35 Soon, this inevitable rejuvenation spreads throughout the planet like a virus.
03:40 Not everyone is afraid of it. Some want to start their lives as old, weak and sick people and end their lives in the spring.
03:48 Others want to experience old age instead of youth.
03:51 In general, life on Earth changes completely.
03:54 The most exciting thing is that presidents and politicians from all countries look like teenagers.
04:00 They are full of strength and energy, but at the same time they go through puberty.
04:05 There are already many conflicts in the world, but when teenagers start to reign, the situation gets worse.
04:12 Only the knowledge of these young people saves the planet from perfect chaos.
04:15 An ordinary teenager lives a storm of emotions and hormonal upheavals, but at the same time they know little about life.
04:22 But in the new world, teenagers have the experience and knowledge of the old wise men, but still have a disastrous control of their emotions.
04:30 Schools are full of elderly people. And if these establishments were once noisy places, they are now strangely calm.
04:38 It is easier to acquire new knowledge at a young age.
04:42 It is difficult to do it when you are old, and that is why school lasts about 20 years.
04:47 You just can't learn fast.
04:49 In addition, you miss all the parties and meetings with friends because your health simply does not allow it.
04:56 As an old person without energy, you spend all your time studying.
05:00 Then, after finishing university, when you have more strength, you start working.
05:06 And the more you work, the more energy you gain.
05:09 Thus, you earn a lot of money.
05:11 And then, with all these finances, you enjoy your youth pension, filled with strength, joy and happiness.
05:19 You have fun, you don't work, and you can take advantage of the knowledge you have acquired throughout your long life.
05:26 But on the other hand, everything can happen exactly the opposite.
05:29 The economy needs young and strong workers.
05:32 The elderly who acquire knowledge at school and university can easily forget them.
05:39 In addition, the older people work slower than the younger ones.
05:43 This can lead to a slowdown in global production.
05:46 If the world realizes that it is impossible to continue like this,
05:49 then, after their birth, the elderly will do nothing for a very long time.
05:54 They will wait for their brains to become more flexible.
05:57 And then, they will only start working.
06:00 And the older they get, the more work they will have to do.
06:03 It is only by becoming very young boys and girls that they will retire.
06:08 The problem with this path is that it is fun to discover the world while you are young and you know nothing.
06:14 But when you are young and you already know everything, it can be a little boring.
06:18 And now, think about it. What is the best thing?
06:21 Spending your childhood and adolescence studying, making new discoveries,
06:25 and spending time with friends or working hard all the time.
06:29 The only thing that will remain unchanged will be that young boys and girls will watch over the grain and take care of the elderly.
06:35 But let's imagine that we have rejuvenation technologies that do not rejuvenate us in an unstoppable way.
06:41 Let's say that we can freeze our age at any biological moment of our choice.
06:45 How would our lives change in this case?
06:48 Many would live 150 and 200 years and youth would last twice as long.
06:53 Everyone would be happy, or almost.
06:56 There is a drawback to this story.
06:58 Today, the rich often live in better health than the young, thanks to a healthy and cost-effective diet,
07:04 expensive drugs and favorable conditions.
07:07 If you are a millionaire, you can easily buy a luxury house in the mountains with fresh air
07:13 and slow down your aging in this way.
07:16 People with the lowest wages live in big cities and inhale gases, exhaust fumes and other harmful substances on a daily basis.
07:23 In addition to a good environment, the rich can afford highly qualified personal coaches, nutritionists and psychologists.
07:31 All these things make the gap between the poor and the rich even bigger.
07:35 And when rejuvenation technologies appear, this gap will become even bigger.
07:40 With the advent of revolutionary pills, genetic engineering scientists could be able to create other privileges.
07:48 For example, pills that would increase your strength or give you a photographic memory.
07:54 The difference between the different social strata would simply become gigantic.
07:58 In addition to their financial situation, the elites would surpass the poor at a physiological level.
08:04 This could lead to consequences as unpredictable as it is.
08:08 On the other hand, let's look at cars.
08:11 A hundred years ago, only the rich could afford to drive such a vehicle.
08:15 But over time, modern transport has become a common currency for most people.
08:20 The same goes for medicine.
08:22 With the development of technology, it may become more accessible to everyone.
08:27 The rich and the poor will then take youth pills before breakfast, like taking vitamins.
08:33 So, let's hope that sooner or later, we will all be able to wake up young again after 70 years of life.
