Why do women live longer than men?

As is known, according to scientists, the probabilitydeath due to problems with the heart or blood vessels in men is five times higher. And if you throw away all the logical arguments about the dependence of the life expectancy of men on their way of life, which in reality are not universal, it becomes completely unclear why women live longer than men. Such an inexplicable discrimination on the part of nature. Ubiquitous scientists and researchers naturally do not want to put up with the unknown (which is understandable, most of them are exactly men), as a result of which they put forward their own theories on this score. Let's consider the most real of them.

Version number 1: Hormone

The main distinguishing feature of the female bodyfrom men is menstruation. It was revealed that during the period of menstruation the woman's organism produces a hormone called "estradiol". This hormone has a great influence on the stimulation of the heart muscles. As a result, during the pregnancy and the second phase of the menstruation cycle, the woman's heart rate is accelerated by 20%. The same effect is exerted by physical cardio exercises. Consequently, regardless of the sporting preferences of a woman, her heart is trained on a monthly basis for several years. As a result, the level of heart problems among women is much lower than among men. In addition, the female body also has differences in terms of genetics, which also protects a woman from aging. All this is the answer to the question - why do women live longer than men.

Version number 2: Genes

There is a version that causes long liferepresentatives of the weaker sex are in the genes of sperm. So the Japanese researchers carried out scientific work and in the winter of 2009 stated that genes that contain sperm play an important role in the matter.

In the course of the research, featureslife of female mice, produced from genes obtained from two female mothers without the participation of the father. Compared with mice born with a natural mix of male and female genes, these mice lived much longer. The creation of mice from two "moms" was done using DNA regulation. Scientists have received the behavior of the gene in the egg of the female is the same as in the sperm. After this, the modified material was inserted into the eggs of adult females to create embryos. The average life expectancy of mice was 841 days. Mice with a natural combination of genes lived only 655 days, which is 186 days less. Moreover, some mice lived from 900 to 1050 days. Newborn mice weighed less than their "natural" siblings, but their immune system was much stronger. As a result, scientists suggested that the reason for the difference in the life expectancy of men and women is in the gene located in the 9 chromosome and associated with growth after childbirth.

Version # 3: Nature

Why do women live longer than men? Some scientists believe that the answer to this question is in the large bodies of men. To ensure victory in the struggle for attention of the opposite sex and the further spread of genes, men are endowed with larger bodies than women. Women do not need to participate in marriage races, as a result of which their body is engaged in more important and useful things, such as optimizing reproductive outcomes, saving energy for producing and growing offspring, etc.

It is not known which of the theories is the most faithful andjustified. And in general, research is a matter for scientists. And we just have to take care of changing the statistics to our advantage, without prejudice to the rest. Therefore, let abstinence from nicotine consumption, maintaining the correct weight, exercising and controlling the pressure, become your faithful companions on the way to the 90th birthday.
