ShootingStar, I meant that I have friends who are excitedly bragging about joining AARP, complaining about their aches and pains, living for the day they can become snowbirds and spend half the year in FL, and saying things like "at our age..."
I agree, you do need balance for your mental health. I dread the day when I can't ride, but that's when I'll be walking outside or doing chair aerobics! (sigh, we used to make fun of instructors who taught that when I worked at gyms). I just don't want to get old. There's longevity in my family, with fairly good quality of life, so I expect to have to adapt my exercise habits as I'll be around for awhile.
