will I be OK in later years or is this something I have to look forward to as I grow older?
You have no clue, do ya?
Getting old sucks. Just slightly better than the alternative.
IDK my late twenties and early thirties were the laziest and fattest I've ever been and I've used my mid thirties to claw back some of that. Really looking forward to my forties, think it could be my best decade yet!
