Scientists find humans age dramatically in two bursts at 44, then 60

The research suggests that aging occurs in at least two accelerated bursts, with significant biochemical changes occurring around the mid-40s and early 60s.

'It turns out the mid-40s is a time of dramatic change, as is the early 60s and that's true no matter what class of molecules you look at.' - Prof Michael Snyder.

'When the scientists looked for clusters of molecules with the largest shifts, they found these transformations tended to occur in their mid-40s and early 60s.'

The study tracked 108 volunteers and assessed 135,000 different molecules and microbes, revealing non-gradual aging changes distinct to specific ages.
