What is the limit of human life expectancy?
In 1961, American biologist Leonard Hayflick discovered that there is a limit to cell division in the human body, and that each cell divides a limited number of times, called the internal biological clock. People call this clock "Hayflick's limit", before cell death, the average cell division 50 to 70 times. It has been found that most human cells divide up to 50 times, once every 2-3 years, so he believes that the theoretical upper limit of life is 120 years.
