(1)We divided it into two groups with 100 people’s support
(2)First, one group was asked to walk 40 minutes three times a week
(3)The other group did 40 minutes of stretching 3 times a week
(4)I made it last for 12 months
(5)We measured the size of the hippocampus before and after the experiment
(6)What was the result of the experiment
(7)When I look at the group that stretched
(8)Seahorses have shrunk by 14 in a year It’s been reduced in size
(9)It’s a result that I expected because it gets about 1 less every year
(10)But what was really interesting was the walking group
(11)This group didn’t decrease the size of the hippocampus, but rather increased by 2 sizes
(12)I’m a year older, but I’m two years younger
(13)The yellow part is the hippocampus
(14)The red line represents the stretching group, where the hippocampus contracted
(15)The blue line represents the walking group, and you can see that the hippocampus is enlarged
(16)Both left and right brains are responding the same way
(17)10,000 years ago, we lived like this
(18)We were hunters and gatherers in Savannah
(19)He was constantly moving, constantly having to find food
(20)They didn’t settle in one place
(21)They didn’t even grow to get food for their lives
(22)Then, they started to grow 10,000 years ago
(23)We achieved industrialization only 200 years ago
(24)And in just 20 or 30 years, we’re building a digital society
(1)It’s easier to understand if you think of human history as 24 hoursimage text translation
(2)Then humans lived as collectors from 00:00 to 23:40
(3)From 23:40 to 23:59:40, I lived as a farmer
(4)Because industrialization took place first, the digital society had to take place
(5)I woke up at 23:59:59
(6)You can think of it as a second that a digital society has been built
(7)Then I can ask you a question
(8)Why do I feel better when I work out
(9)Our ancestors didn’t run to run a marathon
(10)Our ancestors ran to hunt for food or avoid predators
(11)I ran to get to a new land where I could settle down
(12)All of this meant increasing the chances of survival
(13)So, our brains have an increased chance of survival, but when we do things
(14)It compensated us by releasing more dopamine, which made us feel happy
(15)The brain actually thinks that when we’re running, we’re running for survival
(16)The reason why memory is improved is because
(17)Our ancestors hunted, discovered and ran the New World
(18)You go into a new environment, and you see and experience new things while hunting
(19)Because new information keeps coming in
(20)The brain improves memory to store it
(21)If we’re staying in one place
(22)Our brain thinks nothing new is happening
(23)I am often asked what exercise means to you
(24)Here’s what I think.
(25)Let’s take a step back from our advanced lifestyle
(26)You don’t have to think about sports
(27)Exercise is much more fundamental
(28)It’s a way of optimizing the body, and at the same time, it’s a way of optimizing our brain
