Ageing Accelerates at Around Age 50 - Some Organs Faster Than Others
A new analysis of protein changes across human tissues has identified an aging acceleration point around age 50, with blood vessels showing the most dramatic deterioration.

Researchers examined tissue samples from eight body systems in 76 people of Chinese ancestry aged 14 to 68 who died from accidental brain injury, finding age-related increases in 48 disease-associated proteins.Between ages 45 and 55, the most significant shift occurred in the aorta, the body's main artery carrying oxygenated blood from the heart. The team identified one aortic protein that triggers accelerated aging signs when administered to mice. The study, published in Cell, adds to mounting evidence that aging occurs in waves rather than following a steady progression.
