What is the age of a person, after which it is impossible to stop aging
Human aging, like other organisms , is a biological process of gradual degradation of parts and systems of the human body and the consequences of this process. While the physiology of the aging process is similar to that of other mammals, some aspects of this process, such as loss of mental abilities, are of greater importance to humans. In addition, psychological, social and economic effects are of great importance.
Aging - in biology, the process of gradual disruption and loss of important functions of the body or its parts, in particular the ability to reproduce and regenerate. Due to aging, the body becomes less adapted to environmental conditions, reduces and loses its ability to fight predators and resist diseases and injuries.
The science that studies the aging of a person is called gerontology. The term "aging" can be used to describe the social effects of human aging, as well as to describe the destruction of non-living systems (metal aging).
Upon reaching the “critical” age, cell aging cannot stop even the most careful observance of the rules of a healthy lifestyle, no matter how hard you try.
According to Californian scientists, the body of each person, regardless of gender, weight and lifestyle, begins to collapse at the same time - after 39 years . At the same time playing sports, proper nutrition, etc. they give those who have reached this “critical” mark only a feeling of cheerfulness, whereas upon reaching the specified age, cell aging cannot stop even the most careful observance of the rules of a healthy and sporting lifestyle.
Researchers came to this conclusion by calculating that when they reach the age of 39, the human body stops producing myelin. This chemical compound envelops nerve cells in the brain, providing for their protection from external factors and stimuli, and is also responsible for the general condition of the blood vessels, blood circulation, muscles and skeleton.
"With a lack of myelin, unprotected cells die, resulting in a gradual extinction of mental abilities and a violation of musculoskeletal functions, that is, the irreversible aging process starts," the teaching notes.
The defeat of the myelin sheath can lead to numerous injuries, multiple sclerosis and even heart failure, say American experts.
True, many of their colleagues working on the same issue do not think so. On the contrary, they are convinced that the theory of Californian scientists requires careful refinement, as it contradicts the results of earlier studies, which state that the aging process cannot be tied to a certain age.
