Research: Human Aging Occurs in Jumps - with Two Distinct Stages 0 8

A group of scientists from the United States conducted a large-scale study that helped to delve deeper into the mechanism of aging in the human body. The study of this biological process, which involved more than a hundred people aged 25 to 75, revealed that aging is not a smooth process but occurs unevenly, with two distinct stages manifesting approximately at the ages of 44 and 60. During these periods, significant changes are observed in appearance and throughout the body.

According to Professor Michael Snyder from Stanford, each of these age 'transitions' affects metabolism, the immune system, and cell regeneration processes. Over several years, participants regularly underwent tests, allowing for the tracking of changes at the molecular level.

The most significant changes were recorded between the ages of 40 and 60. The first peak of changes, noted around the age of 44, affected molecules associated with the development of cardiovascular diseases, as well as caffeine and alcohol metabolism. The second peak, occurring around the age of 60, was accompanied by noticeable disruptions in the immune system, changes in carbohydrate metabolism, and a decrease in kidney activity. Changes affecting the condition of the skin and musculature were observed in both age phases, indicating the complex nature of the age-related transformation of the body.
