When I was much younger, being old or not was based mostly on the number of years. Now that I'm up there, it's more attitude and physical condition.
I remember being a little kid and thinking that my (then 36 year old) mom was "old"....now that would be a young babe to me, and people would bug me about dating such a young woman....well so would my wife
but I mean relatively speaking.
Not many years ago 60 seemed older to me than it seems now that I'm 60. I definitely don't feel as young as I used to but I'm planning to have at least another 30 good years, hopefully even break 100, and that's time to do plenty more good living...so that idea makes me feel "less old" now. There are SO MANY cool things I've never done but that are still well within my capability for doing, that I can't waste my time worrying about a couple things I can't do anymore. Fortunately, I'm not in bad shape and I have a pretty positive attitude.
