Have you ever paid attention to statistics about life expectancy? And you wondered why women live longer than men? By the way, this question is highly ranked and scientists who are fighting over his unraveling for many, many centuries, whenever putting forward new theory. However, none of them so definitely still unproven... But we still consider them.
Genes. Let us recall the anatomy, the section which says that the genetic information is contained in the genes, which are combined into 23 pairs of chromosomes, 22 of which are the same - both women and men. And only last a couple of different X-chromosome in females and a Y-chromosome in males.
X-chromosome is responsible for the long-standing (even with spermatozoa X chromosome live longer, up to 14 days and Y-chromosome carriers can hold only 5 - 6). Y-chromosome responsible for the variability, the volatility, emotionality, and X-chromosome - this constancy and steadiness, hereditary characteristics. Accordingly, for what will be the children - clever or hereditary diseases, responsible woman. And as a carrier of "genetic baggage" feels (unconsciously, of course) responsibility. Because of this and behave more carefully, more concerned about their health. That's the fairer sex better tolerate pain, and less prone to depression and thoughts of death.
There is another version the difference of X and Y-chromosomes in the "female" genome exist like "duplicate" genes. This enables the female body "replace" damaged gene that, if a man is impossible. Accordingly, it becomes older, the female body is able to be updated, and disease associated with old age, temporary retreat.
Hormones. The male hormone testosterone, responsible for the reproductive function and emotional behavior, gaining a maximum concentration at forty. This is the age in men there is a high mortality rate. Female same hormone estradiol gets the maximum concentration in the middle of the menstrual cycle, that is, virtually every month a woman's life. Japanese scientists believe that this hormone strengthens the heart muscle and the circulatory system as a whole. Because women are less prone to various diseases of the heart.
Also, according to the findings of some American experts, testosterone provokes cancer, particularly prostate cancer. And a negative effect on the cardiovascular system: an old age in men developed hypertension and atherosclerosis. A estradiol helps women to cope with stressful situations and works as an antioxidant that neutralizes the toxic substances produced by cells under stress.
According to researchers, females prefer males, the most "pumped up" testosterone, which in turn turn implies a high probability of a strong and healthy offspring, and these are only young men. That is, its function of procreation they perform in their youth, women continue to be the task - to give birth to, nurture and to "lift" the children and then another raise grandchildren. And because "youth" of women continues.
Emotions. Women experiencing stressful situations easier for them to "reset" because of the fact that often cry, laugh. The men keep all their excitement in itself, and this has a negative effect on the overall condition of the body.
Lifestyle and bad habits. Earlier I spoke of the responsibility inherent in the female body at the genetic level, for which it is more careful about their health. Most doctors visiting less commits reckless behavior, such as, e.g., a parachute jump or driving while intoxicated. Men in this respect more irresponsible. If you are sick, you call a doctor only when it is already out of bed can not stand up. A visit him as prophylaxis - God forbid! Most often, they "calm" with the help of alcohol or cigarettes, too, has not the best impact on health. In addition, a man, if he is sick, is more susceptible to bad feelings, though it has long been proven that disease female body fights longer male.
Height. There is a version that in the "big body" (male) more cells and thus more likely to dangerous mutations. Plus a large body spends more energy, therefore, it will wear out the fabric.
And yet, no matter what the scientists say, or not has prepared Mother Nature, man, take care! You we women are very much needed!
