Many people want to live a long life and be a long-lived old man. Others want to live a long life. Everyone has different standards for longevity. But people ignore one thing, that is, according to the current living standard, the average life expectancy of men in China is 75 years and that of women is 80 years. It is still difficult to live to 100 years old. Long live can only be a daydream, and a person's life is not long. The reference standard is that a person's life span is long as it exceeds the national average life span.
. People don't think that you have to live to be over 90 years old, 100 years old is considered as a long-lived old man. You know, there are still many people in life who leave this world early because of various accidents.
In addition, people now live unhealthy lives and often do things that harm their health and affect their life span. Living to the national average life expectancy is a long life. Moreover, people's life span is limited, and only a few people with longevity genes will live long.
