We are now observing a general trend. It seems that children are getting smarter, but their physique is getting weaker. There are some newborn babies around them, some of whom are very clever. When he was about two years old, he could recite ancient poems and communicate with his parents normally, but his constitution was very weak, that is, he would go to the hospital earlier or take medicine in time, otherwise it would be serious, but in our generation, it was about 20 years ago.
Because modern people's way of life development is more IQ and mental activity than physical activity, there are many office workers, whether in institutions, administrative units or enterprises. They usually just do some documents or do some documents, make planning tables, make design drawings, and sort out all kinds of work in the office, but their mental consumption is relatively high, and their physical consumption is not as hard as that of farmers in the past, so their physical strength.
Now people's strength is generally weakening, which is also an inevitable situation, because in the past, people could easily carry 100 kg, which is true. When their parents were young, it was easy to carry 180 kg. Now young people in their twenties and thirties can't carry 50 kg, and they may feel a lot of pressure on their shoulders because their bones are not strong enough and they don't exercise too much. Natural health is not as good as that of the previous generation, but there is no denying that this generation is indeed better at creative mental activities.
