Why do women live longer than men?

According to the data of the World Health Organization (WHO), the average life expectancy of women is 5 to 7 years longer than that of men. 20 19 the average life expectancy of men in China is 73.64 years and that of women is 79.43 years, with a difference of nearly 6 years. In daily life, women suffer more stress and more chronic diseases (migraine, arthritis, etc. ), more depressed, more anxious, and more likely to be victims of violence. Women's income is lower than that of men, and in many countries, men are still superior to women. Although women have experienced many social inequalities, they live longer than men, which is no exception in all countries and regions.

A traditional view is that men take on more jobs to support their families and engage in higher-risk industries, whether in mines, fields or land farming, which leads to more physical wear and tear, accumulated injuries and shorter life expectancy. If this is the case, then in today's increasingly equal gender, the gap in life expectancy between men and women will disappear, at least it should be narrowed. In fact, even with the great changes in the whole society, the difference in life expectancy between men and women remains stable. Sweden provides the most reliable historical record. 1800 years, the life expectancy of women is 33 years, and that of men is 3 1 year. Today they are 83.5 years old and 79.5 years old respectively. More than 200 years later, women still live 5% longer than men.

Women's physiological advantages make them live longer;

Mitochondrial DNA mutation

Sex chromosome difference

Sex hormone difference

The male immune system ages faster than the female.

Men are engaged in more dangerous industries than women.

Women pay more attention to health care.

Although women are inferior to men in many physical factors, such as strength and speed, men are inferior to women in life expectancy. This is due to the physiological differences between men and women and a wide range of social, psychological and behavioral factors. None of us can control when or how we die, but men can also try to change their lifestyle (such as keeping healthy eating habits, doing physical exercise, avoiding smoking and drinking, etc.). ) to narrow the gap and live a healthier life.

Say a digression:

The average life expectancy of men and women in China is 74 years and 79 years respectively. Women can live five years longer than men, and women can retire at the age of 55, but five years earlier than men.

This is something I still can't understand. European and American countries all retire at the same age.

We can't set up the same age group for both men and women, so that female boxers don't always demand equality in all aspects. So they can continue to work after retirement, and they can retire early if they don't want to work. They don't have to stick to five years earlier and five years later, but they have widened the gap between men and women. The weak go home from work early to take care of their babies.
