Between life and death, how to embrace

　　There is a grandmother theory that can serve as an illustration of the significance of human life expectancy. This theory is about the division of responsibilities between men and women in order to survive in the era of scarcity. Women are mainly storage, they are responsible for collection, and they organize and distribute the collected items. Males are mainly expansive, and they have formed behavioral characteristics and norms that are different from those of females during the hunting process. In this division of labor, the significance of increasing lifespan is reflected: the mother needs to take care of the children, and is also responsible for collecting, in addition to dealing with natural weather changes and the invasion of snakes, insects and beasts, and completing these tasks at the same time requires experience and wisdom. Longer-lived individuals are significantly more likely than younger individuals to survive or help their children survive this environment. The grandmother theory refers to the contribution of more experienced and wise elders in the group to the survival of the group. Compared with the mother, the mother’s mother is more experienced in coping with the environment, and this cycle has formed an evolutionary advantage in longevity.
　　The same goes for other creatures in nature. Take elephant herds as an example. During a drought, those who can quickly find water sources are mostly the elder elephant herd leaders who have experienced drought before. Then the group where the leader belongs will have a much higher probability of surviving than a group led by a young female elephant.
　　This is the impact of longevity on the evolution of human populations.
　　As for each of us, with the improvement of living standards, medical technology has been involved in the extension of life span, anti-aging drugs, stem cells and other technologies have begun to intervene in the natural laws of the life cycle, making human life span dependent on genetics, environment, etc. In addition to the influencing factors, some additional extension methods have been added. But we also know that no matter what kind of technology is used, it is not as useful as adjusting one’s own state. The state mentioned here refers to the diet control in daily life, the strengthening of exercise, and the healthy living habits suitable for oneself, so that the environment in which one lives and one’s own state can reach a harmonious state, which is the basis of health and happiness.
　　The advancement of technology has made human beings have more fantasies about the issue of longevity. The phenomenon of life extension based on wealth is indeed becoming more and more common, but any life will come to an end one day. How meaningful is life extension in the biological category? ? This is also one of the topics that humans have begun to think about in recent years.
　　”Where there is no life or death, how can you embrace it.” Fu Shan realized in his later years, saying that letting go of your arms and letting go of nature is the right way, and don’t deliberately pursue anything. This is similar to the feeling of “died at 25 and buried at 75” said by Franklin, an American scientist who was born decades later. Maybe only people like them can have such an understanding of life.
　　Actively create, not deliberately acquire. This is also a little insight I got from Fu Shan and Franklin’s language thinking. Speak out here and discuss with everyone.
