根据对哺乳动物的寿命、生长及发育期关系的观察和对组织细胞培养的研究,认为人类的自然寿命应在100—175岁范围内。从各国的人口调查来看,有百万分之几的长寿老人达到这一自然寿命。所以多数学者认为人类自然寿命的下限应在百岁左右。然而绝大多数人都过早地衰老了。根据人类袁老生态学的研究,不同人群衰老的基本规律是相同的。从30岁
Based on observations of mammalian life expectancy, growth and developmental relationships, and studies of tissue cell culture, the natural lifespan of humans should be in the 100-175 range. Judging from the censuses of various countries, a few longevity elderly people reach this natural life expectancy. Therefore, most scholars believe that the lower limit of natural human life should be around hundred years old. However, most people are aging prematurely. According to the study of human ecology of old Yuan, the basic rules of aging of different groups are the same. From 30 years old
