Scientists found out the reason of female longevity


Differences in work of a brain and other bodies of men and women can be connected with work and the device of sexual chromosomes. Geneticists came to a conclusion that long life of women can be connected with existence of the additional copy of the gene which is slowing down aging. It is said in article of the Aging Cell magazine. According to WHO statistics, average life expectancy of the person makes 71 years today. Worldwide, from the poorest African states and to the richest countries of Europe, life expectancy of women steadily remains higher, than at men − 73 years against 68 years. According to anthropologists, the specified dependence equally brightly is shown both among the people of a primitive-communal system, and in civilized countries. The phenomenon reason traditionally call that men are more inclined to risk, obesity, alcohol intake, tobacco and drugs because of what they are more subject to heart troubles and vessels. "We think long ago of why women live longer than men. Many people think that this difference between floors has evolutionary roots. In particular, long life allows women to look after longer the posterity and grandsons", − Dubal from the university of California in San Francisco said Dan. Dubal and her colleagues found out that "the gap between floors" is set not only social, but also genetic factors, watching life of mice from the modified DNA. They grew up four groups of males and females, a half of them possessed the "wrong" set of chromosomes – males with XX chromosomes, and females with XY set. Three years of experiences with rodents showed that duration of their life depended mostly not on a sex of an animal, and on a set of chromosomes. Both the "wrong" HH-males, and normal HH-females lived longer, than XY females and males. Thus, the female longevity can be explained not only social and behavioural differences between floors, but also various genetic factors which essence and a role should be studied. Earlier German scientists established that exercises (run, driving the bicycle, swimming) help to prolong life by endurance.
