American scientists have named one more age in which aging of the person can begin. In their opinion, the extinction of mental and physical activity begins at 39 years of age.

At this age, the production of myelin - a substance that protects nerve cells.

Now, scientists should start developing a drug that can maintain the necessary amount of myelin in the body, and thereby stop the aging process.

In 2015, scientists from the University of North Carolina said that at the age of 25 years, a person can see the first signs of aging.

They came to such conclusions after studying the condition of the skin, kidneys, liver, lungs, teeth, vessels and vision in groups of subjects.

According to scientists, from the age of 25 a person should increase physical activity, start monitoring food and regularly visit doctors.
