Signs you're getting old for Classic Car Owners

I just turned 59 3 days ago. "So far" I can still do everything I've always done, although it's much slower and a lot more painful. Although I can still get up off the floor, if Kitty is within earshot, I ain't too proud to ask for help. My hips, knees and ankles aren't the best anymore from years of alignment and suspension work. It takes its toll.
