Mine started late-thirties. Stomach doesn't handle spices as it used to. Any bravery at dinner time means poor sleep and tiredness for a day or two. Bumps/strained things take days to stop hurting.

> In fact most internal organs can’t be felt at all (no nerve endings) That might be technically true, but I think it's worth noting that many internal organs can produce pain, e.g. kidneys, gallbladder, pancreas, prostate, urethra, stomach, intestines, bladder, heart.
Only through chemical means which triggers relatively far away neurons to produce pain. This has the consequence that the pain is not felt at it's source. E.g. a doctor will become very nervous if you report dizziness with a pain moving from your chest into your left shoulder or neck. Such pain originates along the path of the vagus nerve, which includes your lungs and heart (and half the digestive organs, and even t…
I've only opened these comments in the hope somebody here will debunk these findings or at least point out they are dubious... :(

Perhaps not a phase-out program, but a progressive shut-down program, as a trade off between peak performance and total lifespan, where the characteristic patterns of ageing is what allowed humans to live much longer than other animals around the same size. Similar to the idea in this comic: https://www.badspacecomics.com/post/the-suit By this logic, as a hedge against sudden death around ~50, the human body start cr…
I think this argument only makes sense on the surface level. If it was the case that humans hit some hard limit to growth (perhaps running out of 'room' to grow, or losing the ability to process new energy, etc), then I think it could make sense to do this sort of 'graceful decommissioning' behavior, which we'd come to know as aging. But is there a hard limit we hit, aside from the aging process itself? None is obvio…

Agree - I’m 58 and still do the same workout I did in my 30s and 40s including 3 sets of 15 to 20 pull-ups depending on the day. I also still skate (hockey) 2 -3 times a week with a bunch of retired pros (echl, nhl, etc) and typically put up a bunch of points every skate (possibly slightly more assists now but I attribute that more toward enjoying that more these days and not needing to be so flashy)
You are reaping the benefits of having an active fitness regime in your 30s . The average 50 year old who starts exercising today will never get to your fitness level .

There was another recent study that made the front page of HN (would have to search to find it) that found two "peaks" of aging, at 44 and 60. As someone in my late 40s, I certainly identified with that. I was in fairly good shape and feel like, despite some grays and some crows feet, my body was relatively the same from my early 20s to my early 40s. 44 really did hit me like a ton of bricks though - working out got…
It's very likely that aging is driven by some kind of scheduled gene program. It makes perfect sense to phase out individuals from a group-level selection point of view.
So, to rejuvenate the body, you would have to find where the current state of that program is stored, and overwrite it to a younger one, as if using a debugger. So far there are two promising developments about that: Michael Levin's research about bioelectricity, and Harold Katcher's research about exosomes (he seems to have abandoned it, but other people are picking up).

From what I gather, the good news is there is a way, but the bad news is if you haven’t been keeping an active and healthy lifestyle your whole there is nothing you can do, you simply can’t cram decades worth of exercise and nutrition benefits into a few short years all at once and expect to reap benefits.
I think this is bullshit. A poor lifestyle over decades will have consequences but there definitely are benefits to be had in taking up exercise and healthier eating whatever your age.

It is always 20 for me. 4 sets. I am 64. I used to do 30 when I was a teen but I was much lighter then. also lots of swimming, cycling, hiking canoeing etc. etc
