I’ve made it past 50 and (knock on wood) have not experienced any of that.
I made it to 70 (my dad said I wouldn’t make it to 30...LOL)
I “feel” like I’m 50 and if it wasn’t for a prosthetic leg, I think I could do what I did in my 40’s and 50’s...
My wife says I look 50...(she might be biased)....
You’ve jinxed yourself!.......................
