The passage of time may be linear, but the course of human aging is not.
Rather than a gradual transition, your life staggers and lurches through the rapid growth of childhood and the plateau of early adulthood, to an acceleration in aging as the decades progress.
A study identified a turning point at which that acceleration typically occurs: around age 50.
After this time, the trajectory at which your tissues and organs age is steeper than the decades preceding, according to a study of proteins in human bodies across a wide range of adult ages – and your veins are among the fastest to decline.
“Based on aging-associated protein changes, we developed tissue-specific proteomic age clocks and characterized organ-level aging trajectories,” writes a team led by scientists from the Chinese Academy of Sciences in their…
