Ageing accelerates around age 50 ― some organs faster than others

An analysis of how various tissues age is the latest to suggest that ageing does not march to a steady beat.

Now, an exhaustive analysis of how proteins change over time in different organs backs up that idea, finding that people experience an inflection point at around 50 years old, after which ageing seems to accelerate. They found age-related increases in the expression of 48 disease-associated proteins, and saw early changes at around age 30 in the adrenal gland, which is responsible for producing various hormones. Liu speculates that blood vessels act as a conduit, carrying molecules that promote ageing to remote destinations throughout the body.
