Why men live shorter than women

　　Researchers at the University of Michigan released a study on male Lifespan survey reports that men are not nearly as strong as we think. Due to pressure from all aspects, male life span is still being shortened. healthy are under unprecedented threat.

　　This latest survey does not give the difference in life expectancy between men and women, but only states that the probability of death among young adults is higher than that of men. female Three times higher.

　　According to many years of survey statistics by the World Health Organization and the United Nations Population Organization, men's life expectancy is 5 to 10 years shorter than women on average, and in some countries, this difference is still increasing year by year.

　　For example, in our country, men lived one year less than women in the 1970s, 2 years less in the 1980s, 4 years less in the 1990s, and 5 years less in the 21st century. In the United States, general statistics show that men live 7 years shorter than women, and in Russia men live 10 years shorter than women.

　　Why do men live shorter than women? This is a constant topic and fact since human evolution. There is a jingle that goes like this: A man doesn’t shed tears lightly, a man doesn’t like to talk when he has something to say, a man doesn’t go to see someone when he’s sick, a man doesn’t want to go back to his home. In fact, these summaries are far from enough, because factors that cause men to have shorter life spans than women also include other men’s personalities, physiological characteristics and social pressures. For example, men have a high basal metabolism, like to be aggressive, have a poor lifestyle, are competitive, take risks, have high tempers, drink alcohol, etc.

　　1. Eating too much will shorten your life.

　　There are some inherent physiological differences between the sexes. Among them, men's basal metabolism is 5%-7% higher than that of women, that is, their energy consumption is higher than that of women. As early as the 1930s, Clyde, a nutritionist at Cornell University in the United States? McCartney conducted an experiment with white mice. A group of white mice were not provided with sufficient food, but only the nutrients necessary for their survival. For the other group of white rats, sufficient food was provided and they were allowed to eat freely and eat as much as they could. The results showed that the bones of the white rats in the free food group stopped growing after 175 days, while the bones of the white rats in the restricted food group were still growing slowly after 500 days. The average lifespan of the rats in the free-feeding group was only 2.5 years, while the lifespan of the rats in the restricted-feeding group was 3-4 years. Researchers believe that after eating less, the damaging free radicals produced will be reduced accordingly, and the damage to human DNA and cells will also be reduced, so aging will also be slowed down. This may explain why men who eat more tend to live shorter lives than women who eat less.
