Scientists find humans age dramatically in two bursts – at 44, then 60
US findings suggesting ageing is not a slow and steady process could explain spikes in health issues at certain ages
If you have noticed a sudden accumulation of wrinkles, aches and pains or a general sensation of having grown older almost overnight, there may be a scientific explanation. Research suggests that rather than being a slow and steady process, aging occurs in at least two accelerated bursts.
The study, which tracked thousands of different molecules in people aged 25 to 75, detected two major waves of age-related changes at around ages 44 and again at 60. The findings could explain why spikes in certain health issues including musculoskeletal problems and cardiovascular disease occur at certain ages.
“We’re not just changing gradually over time. There are some really dramatic changes,” said Prof Michael Snyder, a geneticist and director of the Center for Genomics and Personalized Medicine at Stanford University and senior author of the study.
“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.”

48 here... i used to be able to read the freaking copyright date on those eye charts ... once i hit mid 40s i need glasses.
I just got progressive bifocals. It was nice to be able to read my watch properly again, but not so nice to have to look down whenever I'm going up or down stairs and to have to move my head around all the time to see all the real estate on my monitor since it's 27".
I've worn contacts for almost 40 years, but got tired of using readers these last several years to be able to, you know, read. After unsuccessfully trying multivocal contacts, I got progressive glasses. My vision? GREAT? The 3 weeks it took to get my brain used to moving my head more and my eyes just right (especially while driving) so that seeing the right part of my prescription wasn't swinging all over the place and making me nauseous? Fucking hell. That was absolute torture. It's worth it on the other side at least.
I do kinda miss contacts. I may get a second opinion for my prescription and try again.
In less than 2 years (in my early 40s), my eyes went from better than 20/20 with great close up, to barely 20/20 with astigmatism and I need readers
My eyes started losing strength when I was 15. 10 years later, I still got my near sight vision, but I know that will be gone in about 20 years from now…
