Some cars can still drive on the road for decades, and some cars are scrapped after only two years of driving. It is related to the quality of the car itself, to the operation and maintenance, and of course to the mileage. So is the human body. Young people are not necessarily healthier than people over 500, but also depends on how you "use" your body. I think there are several reasons:

First, Lin Daiyu's destiny takes a hand constitution.

Some people have genetic advantages and are born with good physique. They are over 500 years old, but their body functions work well, so they are in good spirits. Some people are born weak, and they should be as bright as summer flowers, but they fall like autumn leaves. This cannot be changed. We must admit that genes decide everything. I don't want to be in poor health.

Second, all the consequences of the decline of youth are self-inflicted.

Some young people, while young, do whatever they want with their bodies, thinking they can handle it. For example, staying up late to play games, chasing dramas and playing mobile phones. For example, in the cold winter, show your thighs for beauty. For example, addicts generally drink carbonated drinks, milk tea and snacks. What's bad for your health? Young people's self-control ability is not as good as that of middle-aged and elderly people, and they are more likely to break down their bodies because of bad living habits.

Third, middle-aged and elderly people have entered a long road to health.

Middle-aged and elderly people take care of themselves carefully because they know that they are no longer young. In order to keep healthy, he became an expert. From diet to exercise, living habits are very healthy. Moreover, self-control is stronger than that of young people, and they will not be easily defeated by desire, and they can be self-disciplined.

To sum up, some people are weak at a young age, and their spirits are not as good as those in their 500 s. Still should cherish your body, after all, life is only once.
