Ever since I was in my 20s, I've noticed "old geezers" have the most fun, with contra dancing, ski clubs, etc. It seemed like all the younger people wanted to do was get drunk. Now that I'm in my 50s, I've pretty much caught up with them in age - but now I hear a lot of whining about aches and pains, and it drives me crazy. I think as far as this particular thing is concerned, people inflict ageism on themselves.
I don't know who I would prefer to date - a whiner or a drunkard. Actually, I prefer neither.
