There come moments in a person’s life when the body seems to malfunction, and troubles appear one after another.
But this is not a sign that strangers have jinxed or spoiled you. American scientists have concluded that the processes are associated with reaching a critical age.
The existence of a critical age and the time frame that determines it were calculated by employees of Stanford University (USA). The results of the work were published in the journal Nature Aging.
Critical age
Geneticists have come to the conclusion that upon reaching a certain age, the number of molecules and bacteria in the human body changes.
The changes are associated with the functioning of internal organs, which leads to a variety of problems with the immune system, metabolism, heart function, the condition of blood vessels and other organs.
Danger points
As part of the research, observations were made on more than a hundred volunteers aged 25-75 years.
They regularly gave blood for analysis over several months. Observations were conducted from 1 year to 7 years.
A wide variety of changes were monitored (RNA, protein, metabolism, microbiome, etc.).
As a result, over 135 thousand changes in the state of molecules and bacteria were recorded, and in total more than 250 billion indicators were obtained.
Geneticists have come to the conclusion that the processes are associated with age and are most pronounced at certain years of life.
Most often, shifts occurred at 40 and 60 years of age.
40 years old
At this age, changes were observed in the composition of molecules associated with metabolism (alcohol, caffeine and lipids), heart and vascular diseases, skin condition, and muscle tissue.
60 years old
At this age, changes were associated with carbohydrate metabolism, caffeine metabolism, the immune system, kidney function, heart and vascular diseases, and the condition of the skin and muscles.
Scientists advise that once you reach this age, you should start paying more attention to your health.
