Do you know why women live longer than men?

Women can live a few days longer than men under the same conditions of not eating or drinking. British scientists have found that most species are females and live longer than males.

Woman, you call it cowardice? If there are still men who think that women are the weak sex today, it is quite speechless-it has been proved that women are more tenacious than men in terms of stability and ecological ability from birth to old age: men may run faster and lift heavier objects than women, but the average life expectancy of women is 5-6 years longer than men, even 10%. At the age of 85, the ratio of women to men is 6: 1. By the age of 100, the ratio of the two is more than 2:1; By the age of 122, the current world record is 1: 0, and women are the winners.

Then why do women live longer than men? One view is that men go to Elysium early to rest in peace because of the hardships of life and the pressure of work. Today, when men and women are more equal, you might expect this death gap to disappear, or at least decrease. Unfortunately, there is no evidence that this phenomenon exists. Today, women still live longer than men, which is exactly the same as the situation that mothers who are housewives live longer than fathers who go out to work. Moreover, no one really believes that working fathers will do more harm to their health than doing housework. According to the existing statistics, married men have more advantages than their wives, and married men can live longer than unmarried men, while married women only live a little longer than single women. So who's life is actually easier?

Perhaps the possible reason is that women are healthier and live longer than men in living habits, such as smoking less and drinking less, and eating more carefully. But now more and more women smoke, and there are many women who love to drink. Even eating junk food is more difficult to distinguish each other, but women are still healthy and live a long life! So lifestyle determines the length of life, which is not the answer to the question. Thomas Kirkwood, director of the Institute of Age and Health of Newcastle University in the United Kingdom, studied this problem from a wider biological perspective by observing other animals, and found that most species are females and live longer than males, which also shows that the explanation of human male and female life expectancy may be rooted in biology. Many scientists believe that people's aging process is gradually accumulated due to a large number of small problems-DNA chain damage, protease disorder and so on. The accumulation of this decline means that the length of our life is controlled by the balance between the degree of cell damage and the efficiency of cell repair. The mechanism of body self-maintenance and cell repair is really amazing-that's why we can live for so long-but these mechanisms are not perfect, and some injuries are irreparable and will accumulate over time.

Long, long ago, our ancestors who lived by gathering and hunting had to constantly fight hunger. The energy needed to maintain immortality is far from the requirements. In the case of scarce energy, our species can only choose to grow and reproduce naturally and put eternity aside. Our genes only regard the body as a short-term tool.

Professor Kirkwood's laboratory research shows that compared with short-lived animals, long-lived animals have better maintenance and repair systems and are smarter than the latter. The same is true of human beings. If we want to live a long life, we need clever ways to avoid various environmental disasters, so the corresponding disposable body will be reduced and the energy for repair will increase. From a biological point of view, it makes sense for women to live longer than men, because her physique plays a key role in improving the health level of future generations. The fetus grows in the womb and the baby needs breastfeeding. These special properties will also bring some compensation to women. Just as women's monthly "official holidays" have also created women's endurance and viability, and also created a much stronger hematopoietic function than men. Under the same conditions of not eating or drinking, women can live a few days longer than men, and their special physiological conditions determine their high tolerance and strong viability. In addition, women love to cry, and when they cry, they just release a lot of bitterness, sorrow and anger in their hearts, which is very good for the tissues in the body, while men usually have tears and often bury these unfavorable factors in their bodies, which is extremely unfavorable to health. The so-called anger and anger are the crux.

Researchers at the University of Michigan in the United States pointed out in a report that the mortality rate of mature men is three times that of women. The reason is that the female population in the United States is 6 million more than that of men, with an average life expectancy of 7 years, and fatal diseases such as heart disease, cancer, pneumonia and liver cirrhosis are twice that of men. Another factor that leads to women's longevity is that women are protected by their estrogen, which will increase their cholesterol level, help slow down brain atrophy, improve sleep quality and enhance gene repair. In addition, women have a high proportion of genetic variation related to longevity, which helps to reduce the risk of disease.

From an evolutionary point of view, successful mating between men and women does not promote longevity. In fact, high-quality testosterone can improve the fertility of men, but it is harmful to long-term survival or longevity, because the repair of cells in the body is more difficult than that of women. The research report also pointed out that people who walk fast will live longer, because legs are the transportation hub of the body, which contains 50% of the nerves, blood vessels and circulating blood. Such an old man must have a strong heart. In order to make both men and women live longer, it is extremely important to maintain an optimistic lifestyle. People who spend more time in sports and social activities every day will live longer than others.
