In fact, those who live to be over 100 years old are considered as long-lived old people. Most of us live to be about 70~80 years old, and those under 100 can be said to be very long-lived old people, while the limit of 100 is about15 years old. According to scientific research, the main reason why these long-lived old people can live to 1 10 years old is that the number of bifidobacteria in the body is as high as 95%, and the content of bifidobacteria in the human body is closely related to the growth, metabolism and even illness of the human body. According to scientific research, the physical condition of the elderly over 100 was investigated, and it was found that there were many bifidobacteria in their bodies. So some science shows that human life seems to be closely related to the number of this bacteria, but what it actually looks like may need more scientific research and investigation.
Perhaps many of us have the desire to live a long life. On the one hand, longevity may really be affected by the number of bifidobacteria in the body, on the other hand, I think it is also related to people's living habits, whether people are happy psychologically, whether they are satisfied all their lives, and so on. Generally speaking, people who are satisfied with their lives, people who don't have much troubles may live longer, and people with good living habits and good health will have a higher probability of living longer. So no matter what, you must protect your body at ordinary times.
