I will soon be 71 and feel great! People tell me I appear to be about 60 (hey, l I'll take it) but that is probably because I lost 24 pounds and I still have a full head of thick brown hair (just an ever so slight amount of grey starting to appear). I am still pretty agile, still very active and still pretty strong. I still do everything around the house that includes lifting, cleaning, fixing, building, etc. Other than cheaters for reading, I don't even wear glasses.
I also pride myself for my sense of humor! Some don't get it or think I am being sarcastic, but I find humor in almost every aspect of the day. To me laughter is the best prevention and best cure. Thankfully, I also have good genes and DNA. Hopefully I will be around for another few decades. Got plenty of ammo left to fire - lol.
