I think it's mainly because men don't love themselves, don't pay attention to self-protection (pay attention to health as soon as possible), are too obsessed with women and don't know how to control themselves. Men are under greater pressure in society than women. They have to resist the pressure of work and entertainment outside, and satisfy their wives' desires inside (of course, men also have factors such as self-restraint, accommodating women, neglecting themselves, etc.), do not pay attention to exercise and practice, daydream all day, and are caught between inside and outside. Without a glimmer of hope, women don't have so many factors to promote their own corruption, so natural women live longer than men. Most of the hard work is done by men. Snow mountain checkpoints, coal mines, underwater and other harsh environments. Other statements are likely to be deceptive. In addition, the social environment and the cultural environment of public opinion are not conducive to men's life and health. In addition to the few bad habits such as smoking and drinking, the most important reason is that women have immune advantages.

Compared with men, women's immune system is more complicated. Women have more immunoglobulin M than men, and their natural immune defense function is stronger, and fewer people suffer from immune deficiency than men. The immune system is closely related to chromosomes. There are many genes related to immunity on chromosome. If some genes are defective, the structure or function of the immune system will change accordingly, thus obviously weakening the immunity of the whole human body. We know that the male chromosome is "XY" and the female chromosome is "XX". If there is a gene that affects life span on one X chromosome, there is likely to be a modified gene on the other X chromosome, so the congenital genetic influence of women is greatly reduced. Of the more than 200 known genetic diseases, 75% are male, and only 25% are female. In particular, hemophilia caused by the deficiency of the eighth coagulation factor basically occurs in men. In addition, red-green blindness, legume diseases, hemolytic anemia, hereditary deafness, congenital agammaglobulinemia and other diseases. Also tend to "prefer boys to girls." In particular, immune genes mainly exist on X chromosome, and women have two X chromosomes, so it can be considered that women's immune system has double insurance, at least twice as strong as men's. Better immune function makes women live longer than men.
