Since when does 50 y.o. equate to "elderly"?
Although my 20-something kids say I'm old. I once thought of 40-something as old. It's all relative, I suppose. Mental age and physical age never match, do they, until advanced age onset, dementia, etc. I'm still a 20-something in my head. Like @
canklecat says, use it while you can. That's why I'm getting back into training. I want to have an active and productive retirement.
