Shooting Star, I will not get "over it" anytime soon. I am heading toward 55 and I still find I have more in common with younger people. Except for my cycling friends, all of my other same age friends are fat, unfit, and fairly uninteresting. I mean, they are nice people I've known for many years, but we seem to have less and less in common as the years go by. They seem to think that being older means that these negative changes are inevitable. Both myself and my husband have our share of age related health issues and we do not let these things stop us from being active.
I don't want to be 20 again, or even 35, but you will never find me in an age segregated community. I view AARP in the same way. Maybe I'll feel differently when I'm 65 or 70, but I doubt it.
