The body "wearing down" is not a thing. You're talking about repetitive stress injuries. The body is built to work as long as you need it to, and replenish itself daily.

This is so obviously wrong that I wonder if you are deliberately trolling. You can just look at wrinkling skin, decreased peak performance and all the other pieces of evidence that the regerative abilities of the body degrade after age 30-40. Or you can look at the thousands of papers in the areas of cellular senescence and its many consequences: DNA damage, lipofuscin accumulation, glycoxidation, lipid peroxidation of the inner mitochondrial membrane, atherosclerosis and probably dozens of other processes that translate to the "body wearing down".

A.K.A. sun damage

> decreased peak performance

Peak performance happens once. That's a mathematical truth. Just because something isn't operating at peak performance doesn't mean it's "worn down"

There's lots of evidence that people acquire damage throughout their life. And I would certainly agree that as you approach 100 years old, the repairing slows down.

I'm just saying someone who is in their 50s and saying their body has "worn down" is not in that situation. They damaged their body. If you're 80 years old it's a different story.
