Agree. I need two new knees in the near future. I was (for decades) an avid downhill skier and runner, so it’s not surprising. BUT I would have still skied and run, knowing that in my 60’s I might need new knees. I might feel differently if it was my brain that was affected by my activities, but more stats on the general population would be interesting at the very least.
Yeah. Had a new hip 8 yes ago. Pretty much everybody on Mom’s side of the family get new ones in their 50s.
