I have talked about the subject like the title in fact in my book about 14 years ago. Looking back now, there are places where I nod and why.
1. Genetic factors
2. Social and behavioral factors
3. Environmental factors
4. Mental factors
5. Physical factors
In a very brief explanation, 1 is a person who has a gene of longevity and can not do anything about this. Regarding social factor of 2, it refers to a stable family life, friendship, or connection with society. Behaviorally, there are overseas data that people with anger and those with aggressive personality are likely to progress atherosclerosis. Excessive drinking also shortens the life span, so I think it is important to know the appropriate amount.
The mental factor of 4 is to think about measures to prevent aging of brain cells. On my own terms, I feel that 3 and 5 actually affect individuals most.
For 3, a person who does not smoke, for example, by smoking clean air, not approaching places and environments where it is easy to meet accidents, saying that you do not smoke, when you ride a car seat belts, job-related work and exercise It is not recommended, etc.
Regarding the physical factors of 5, it is better to exercise not only thinking about things like aerobic exercise but also enjoying and doing it for a long time. Even in golf, tennis or swimming, I think that I will continue doing things I like. I hope to continue with the fitness using the gym instruments, can I still be old? about it. Those who are not good at exercising, I think whether walking, only walking while shopping.
And regards to eating habits, I often see comments from the experts that people with less calorie intake will live longer, do you all know? This is an experimental result that is confirmed only by a mouse or a small creature. In the history of medicine research, there are many examples that even if I think that a good medicine was found in mouse experiments, it did not work for human beings at all. For humans, I do not yet know whether excessive calorie restriction, high protein diet is really good.
