This is the exact age when our body's aging begins to accelerate

A new scientific study conducted by Chinese researchers reveals that the human body begins to age more rapidly around the age of 50.
The adrenal gland, for example, undergoes changes as early as age 30. But it is between ages 45 and 55 that a major biological turning point appears to occur: the expression of aging-related proteins increases sharply in several organs, particularly in the aorta, the body's main artery.
One protein in particular, called GAS6, may play a central role in this process. Its injection into young mice during scientific experiments caused early signs of aging, such as muscle weakness, balance disorders, and vascular damage.
"Blood vessels may act as channels that diffuse aging throughout the body," Guanghui Liu, lead researcher, wrote in the report published in the medical journal Cell .
Scientists analyzed nearly 516 tissue samples from 76 donors aged 14 to 68, all of whom had died from head trauma.
Their research focused on several major organs, including the cardiovascular, digestive, immune, endocrine and cutaneous systems.
The study identified 48 proteins associated with aging and chronic diseases, such as cardiovascular disorders, tissue fibrosis, and liver disease. These proteins become increasingly prevalent with age, according to their findings.
Because these proteins are not uniform throughout the body, researchers have found that some organs show signs of aging before others.
These results support the idea that aging does not follow a linear curve, but rather occurs in waves, with certain critical thresholds.
Other experts, however, point out that it is still too early to designate 50 years as a universal tipping point.
Researchers hope this study will lead to the development of targeted interventions to slow aging and improve long-term quality of life.
