When it comes to a person's life span, we will find that almost no one will say it at ordinary times. Only when life expectancy declines will this matter be put in the most important position, even at the expense of one's life savings in exchange for that short life extension.
One of the most famous longevity stories in history is the story of Qin Shihuang cruising for immortality, which shows that there is no immortal elixir. We still need to look at the problem of longevity from a scientific perspective, instead of blindly believing in something almost impossible.
We all know that everyone develops from a fertilized egg. After numerous divisions, the intermediate cells gradually form various parts of the body, and they need to get nutrients from food constantly, and their breathing almost never stops.
In the long life, the body may encounter all kinds of situations, some of which may have a bad influence on the body, thus indirectly having a negative impact on the life span, and only some things within an appropriate range may have a positive effect on the body, that is, a positive impact.
The relationship between fitness and longevity is more complicated, because longevity will be affected by other factors at the same time, so just like the open ending of a movie, every step may have an impact, but through people's past experiences, we can sum up some reliable experiences.
Anyone who knows about fitness should know that although Schwarzenegger is now in his seventies, he is still full of energy and looks totally out of line with his real age. This can't say that he has no fitness function, but it can't be completely fitness function. He is very self-disciplined.
As mentioned above, if fitness is in a proper range, it will have a positive impact on the body and keep it in the best condition. Objectively speaking, this is an extension of life, and it may take a long time to show it.
However, due to different fitness goals, many people may complete some training that is not good for their health. For example, a long run, regardless of their physical condition, will gradually have a negative impact on their health and gradually shorten their life span.
Of course, it is more likely that the lack of fitness exercise makes the body in a sub-health state for a long time. Although it doesn't seem to be a big problem, it may break out after the annual ring of time continues to rotate and the physical condition gradually declines.
