Biomolecular shifts occur in our 40s and 60s (2024)

Truth is many people also stop moving (exercising) significantly in their forties (reason being probably sitting lifestyle promotes posture and fascia degradation which makes moving less and less enjoyable).

I'd posit that another significant decline in moving occurs in the sixties when many go in rent.

Not sure if the biological clock is cause of abrupt changes or rather our scheduled lives. So, no significant changes from the sixties on? Then what's the genetic function of those programmations?

People who reach old age (100+) are mostly also comparatively healthy.

Without writing a book about it I'll just say that I think the most important thing is people shouldn't look at this info and conclude that their body's going to fall apart no matter what.

I'm in my mid 40s and in the best shape of my life, lots of energy, aches and pains from my late 30s have all disappeared, to get there it took diet and exercise changes that were surprisingly modest. For me it was mostly weights, a little bit of cardio, and cutting back on my worst episodes of caloric excess.

I have friends who didn't do any diet and exercise interventions, and are starting to look like hell and complain about the "inevitable" consequences of aging.

And then there are those jacked dudes in their 70s who are hitting the gym 5 times a week, I can only aspire to be as healthy as them at their age.

Use it (with proper care and feeding) or lose it.

I'm sure there's also an important component of luck and general health there.
