Life span refers to the maximum length of human life. This length is about 120 years old; Some studies have concluded that it is equivalent to about 5 ~ 7 times of a person's growth and development period. On the one hand, the length of life is restricted by socio-economic conditions and the level of medical care, which varies greatly in different societies and periods.
On the other hand, due to individual differences in physique, genetic factors, living habits and living conditions, individual life spans vary greatly. The average life index is often used to reflect the length of life, and sometimes the average life is calculated. Life expectancy is one of the important indicators to measure the quality of population.
10 2020 10 On October 28th, the State Council held a press conference on the reform and development of health undertakings in the 13th Five-Year Plan. From 20 15 to the end of 20 19, the average life expectancy of China residents increased from 76.3 years to 77.3 years, which means that it increased by 1 year in four years. During the 13th Five-Year Plan period on March 5th, 2002 1 year, the average life expectancy in China increased from 76.3 years to 77.3 years, an increase of1year. The government work report puts forward in the outline of the objectives and tasks of the 14 th Five-Year Plan that the average life expectancy will increase by 1 year.
According to the latest joint research by Roseveare Park Cancer Research Center and the research team of Singapore Biotechnology Company, the life span of human beings can reach 120 years old and the upper limit is 150 years old. The length of life is influenced by many factors. The strength of innate endowment, acquired training, living conditions, social system, economic conditions, medical and health conditions, etc. Will have an impact on human life.
There is no scientific basis for accurately estimating an exact upper limit of life. Now the life span of human beings is changing. Physiologically speaking, life span is no longer a fixed constant, but whether it can be extended indefinitely remains to be scientifically studied. As the founder of material civilization and spiritual civilization, human beings have been breaking the limits of life for a long time. It is believed that there are two factors that determine human life span: one is our biological age; The second is the ability of self-recovery.
