It can only be said that women are more careful and have more development potential in economics.
Why are zombies generally male and ghosts female? Do ghosts floating in the world have wronged or wronged souls? In feudal society, women had no status and were often bullied and persecuted, so there were more female ghosts. The female ghost is very beautiful. If a female ghost is as straight as a zombie, it will not look good, so most of the authors turn zombies into men.

Why? Men usually die first! Researchers at the University of Michigan in the United States released a survey report on men's life expectancy, saying that men are far from being as strong as we thought. Due to various pressures, men's life expectancy is still shortening, and men's health is being threatened as never before.
The latest survey does not give the difference in life expectancy between men and women, only that the death rate of young men is three times higher than that of women. According to the survey statistics of the World Health Organization and the United Nations Population Organization for many years, the average life expectancy of men is 5 to 10 years shorter than that of women, and this difference is increasing year by year in some countries.
For example, in China, the life expectancy of men was less than that of women 1 year in the 1970s, 2 years less in the 1980s, 4 years less in the 1990s and 5 years less in the 20th century. In the United States, general statistics show that men live seven years less than women, while in Russia, men live seven years less than women 10 years.
Why do men live shorter than women?
Why do men live shorter than women? This is a constant topic and fact since human evolution. There is a saying in a jingle: Men don't cry lightly, men don't like to talk, men don't go to see when they are sick, and men don't want to go back when they have a home. In fact, these summaries are far from enough, because the factors that lead men to live shorter than women also include other men's personality, physiological characteristics, social pressure and so on. For example, men have high basal metabolism, love to be brave, poor lifestyle, aggressive, adventurous, angry and addicted to alcohol.
1. Eating too much will lead to short life.
There are some physiological differences between men and women, among which the basal metabolism of men is 5%-7% higher than that of women, that is, the energy consumption is higher than that of women. As early as the 1930s, Clyde, a nutritionist at Cornell University in the United States? Myka did an experiment with mice. A group of mice were not given enough food, but only the nutrients necessary for their survival. On the other hand, give another group of mice enough food to eat freely and eat as much as possible. The results showed that the bone growth of rats in the free diet group stopped after 175 days, while the bone growth of rats in the restricted diet group continued slowly after 500 days. The average life span of mice in free eating group is only 2.5 years, while that in restricted eating group is 3-4 years. Researchers believe that the harmful free radicals produced after eating less are correspondingly reduced, and the damage to human DNA and cells is also reduced, so aging will also slow down. This may explain why men who eat more always live shorter lives than women who eat less.
2. Without sun protection, you may lose your life.
Compared with women, men's lifestyle is neither scientific nor healthy. For example, men like to smoke and drink, and cigarettes and drinking have become the most vicious killers of human life and health in modern society, and the harm to men is far greater than that to women. The life expectancy of Russian men is much lower than that of women, and vodka plays an important role. In addition, men's eating habits are often voracious or overeating, so the incidence of gastric diseases in men is 6.2 times higher than that in women on average. In addition, men usually eat more fat and protein food than women. Studies have shown that eating too much fat and protein is an important cause of rectal cancer. At the same time, a considerable number of men do not pay attention to sun protection and skin cancer examination, so the probability of men dying of melanoma is twice that of women.
3. Men are too aggressive.
Androgen in men's blood is an important reason for irritability and aggression. In the war years, there were many men on the battlefield, which naturally made it easy to understand why men were so short-lived, because the war took a large number of men's lives. However, in peacetime, men's aggressive personality is also an important reason for their sudden death, so their life expectancy is shorter than that of women. For example, men are twice as likely to die in a car accident as women because of being competitive and drunk driving.
A survey in Sweden shows that 70% of the casualties on expressways are caused by male drivers, and 60% of traffic accidents in cities are caused by male drivers. Statistics of traffic accidents in Spain show that the proportion of male and female drivers in traffic accidents is 60% to 40%. Statistics from other European Union countries and the United States show that the traffic accident rate of male drivers is higher, about 70%, while female drivers only account for about 30%.
The reason is that androgens in men are at work, which often urges men to show off their talents and at the same time satisfy their psychology: you see, my driving skills are superb, and the other person is simply a melon, with poor skills and occupying the road. The result of this is often overtaking and colliding with the normal driving vehicle in front, resulting in the destruction of the car and the death of people. In this respect, women are just the opposite, and it is almost impossible to have an accident. The direct victim of a car accident is the driver, so there are far more short-lived men than women.
Menstruation exercises a woman's endurance.
Compared with men, women love to cry, and if men cry often, they will be considered weak, unmanly and not strong, so men dare not cry, which has a great impact on health and longevity. Tears can not only relieve stress and emotions, but also help to expel toxic substances from tears. Of course, the result of men's tears is the deterioration of their bodies, which will also have a negative impact over time.
In addition, women's special physiological phenomena also determine their high tolerance and strong viability. For example, women's menstrual period has exercised their endurance, especially their ability to survive in disasters. In the case of not eating or drinking as much as losing blood, men may die a few days or even earlier than women, and women are more likely to persist until rescuers arrive, thus successfully surviving from the disaster.
5. Attitude determines life span
The biggest reason why men don't want to go back to their hometown is that society requires men to stand tall. In order to succeed and support the family, men must work and pay too much, asking men to put up a facade at work or at home. Therefore, men are more nervous than women at work and bear more pressure than women. Therefore, the hospitalization rate of male patients with myocardial infarction is 7- 10 times that of female patients.
Finally, men's attitudes towards health and body affect their life span. A survey in the United States shows that 82% of men regularly maintain their cars, but only 50% of men have regular physical examinations. This has caused men to be unaware of minor illnesses, moderate minor illnesses, and sudden death from serious illnesses. If men can find their own physical abnormalities in time and diagnose and treat them in time, then the morbidity and mortality can be greatly reduced.
Although it is an indisputable fact that men live shorter than women, as long as men today follow the four principles of healthy living, they may live longer, even longer than women. These four principles are: reasonable diet, moderate exercise, quitting smoking and drinking, and psychological balance.
According to the population statistics of many countries in the world, the average life expectancy of women is 5 ~ 10 years longer than that of men. Why do women live longer than men? People analyze from the following aspects:
Relationship with sex chromosomes: Among the 23 pairs of chromosomes in men, the sex chromosome is XY and the face chromosome in women is XX. Some genetic diseases are passed on to the next generation through sex chromosomes, which is called sex inheritance, such as hemophilia. If the pathogenic gene is on the X chromosome, it is recessive, and the homologous gene of another X chromosome can protect women from this disease. In addition, there are several immunoregulatory genes on X chromosome. Then, women have twice as many of these genes, and after one group is damaged, the other group can compensate. Therefore, women's immune system will decline later, and fewer people will die from cancer and infectious diseases than men. According to Japanese statistics, the cancer incidence of women is 1.33 times lower than that of men, so the average life expectancy of women is also long.
Relationship with women's physiological state: the law of women's delivery and menstrual blood loss can be regarded as a kind of physiology, which makes women's hematopoietic function stronger than that of men and lasts longer.
The relationship between women and estrogen: estrogen can protect the blood vessel wall and prevent it from becoming hard and brittle, while men's body reacts more strongly to vasoconstrictors such as adrenaline than women, so men have more chances to suffer from cardiovascular diseases than women. According to Japanese statistics, women suffer from heart disease 1.07 times lower than men, and cerebral hemorrhage 1.04 times lower than men.
Another data shows that a group of elderly women over 90 years old found that there were 6 diseases on average, while men of the same age had 8~9 diseases on average.
Relationship with lifestyle: Men smoke and drink more than women. In addition, men are engaged in high-risk jobs, such as high-altitude and high-temperature operations, metallurgy and electricity, and there are more work-related injuries and accidents than women.
Relationship with basal metabolism: the basal metabolic rate of women is lower than that of men after 25 years old, and it is not similar to that of men until after amenorrhea. Generally speaking, the metabolic rate in life is lower than that of men. It is estimated that energy metabolism can be reduced by 30 ~ 40%, and high energy metabolism can promote life extension, which has been confirmed by experiments.
The life expectancy of women seems to be higher than that of men, which is caused by many factors. In the animal kingdom, females also live longer than males. For example, the average life expectancy of male rats is 483 days, while that of female rats is 80 1 day; The male and female of Daphnia magna (65438 08℃) survived for 38.6 days and 44.7 days respectively. The average life span of black spider male is 100 days, female is 27 1 day, corn borer male is 60 days, and female is 1 1 day. This shows that it is a universal law in the animal kingdom that females live longer than males. And human beings have to add social factors and lifestyle differences.
Cooking at home is usually done by women. Why are there so many male cooks? Women are good at cooking at home, and cooking is generally not as capable as men, especially this is a hard job.
Why do men usually have chest hair? Because men have more androgens, of course, there are also many chest hairs.
Why do men usually mention breaking up, while women mention that men only want this family to be good after marriage? Men here don't mean all men, but some hehe.
Why are philosophers generally men? From the perspective of equality for all, gender does not affect thoughts, but gender only affects thoughts.
From the perspective of women, everything in reality is beautiful or cruel. They don't ask themselves what's going on, but do what they want. Naturally, there are not so many philosophical problems.
In a sense, just because men are always changing their minds doesn't mean they are changeable. Instead, I think that my understanding of something is correct, and at the same time I find that I am wrong. Constant re-understanding has produced philosophy. Because men and women have different personalities, this obvious change will occur.
