What age is a person after which aging cannot be stopped
Human aging, like the aging of other organisms , is a biological process of the 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 the physiology of aging of other mammals, some aspects of this process, for example, loss of mental abilities, are more important for 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 deal with predators and resist diseases and injuries.
The science that studies human aging 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 (aging of metals).
Upon reaching the "critical" age, cell aging cannot be stopped even by the most careful observance of the rules of a healthy lifestyle, no matter how hard you try.
According to California scientists, the body of every 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. give those who have reached this “critical” mark only a feeling of vivacity, while upon reaching the indicated age, cell aging cannot stop even the most careful observance of the rules of a healthy and athletic lifestyle.
The researchers came to this conclusion, having calculated that upon reaching 39 years the human body ceases to produce myelin. This chemical compound envelops nerve cells in the brain, providing for their protection against external factors and stimuli, and is also responsible for the general condition of blood vessels, blood circulation, muscles and skeleton.
“With a lack of myelin, unprotected cells die, resulting in a gradual extinction of mental abilities and impaired musculoskeletal functions, that is, an irreversible aging process is launched,” the teaching notes.
Damage to the myelin sheath can lead to numerous injuries, multiple sclerosis, and even heart failure, American experts say.
True, many of their colleagues working on the same issues do not think so. On the contrary, they are convinced that the theory of Californian scientists needs to be carefully refined, since it contradicts the results of earlier studies, which say that the aging process cannot be tied to a certain age.
