Few of us will refuse to prolong our youth. But when does the body really start aging? On this occasion, quite fierce discussions have been conducted between scientists for a long time. However, according to the latest data, the aging process begins on average in a person at 39 years of age.
More recently, WHO experts believed that youth lasts until the age of 44, and maturity begins closer to 45. Old age begins after 70 years. However, American scientists believe that we should not delude ourselves.
From the age of 39, regardless of gender, health, weight and other factors, the aging process begins. This is expressed primarily in a sharp reduction in the production of myelin, a substance that protects nerve cells from aging and the harmful effects of external factors.
During the experiment, scientists from the United States observed volunteers aged 23-80 years, who performed various exercises on assignment, while the experts at that time compared the speed with which the groups under study performed the movements.
It is then that the deterioration of the physical capabilities of the body begins, the first signs of the extinction of mental abilities are noted. Moreover, one of the adverse consequences of damage to the myelin sheath of neurons can be the development of multiple sclerosis, writes "Moskovsky Komsomolets".
However, many scientists disagree with this assumption. For example, some believe that the onset of the aging process depends on many factors, from the environment to the level of stress. In addition, an important role is played not only by heredity, but also by gender. So, there is a version that women still age later than men, which explains their longer life expectancy compared to the stronger sex.
