I'm older, cranky, and adverse to extreme temperatures. So, in my new home town climate, I stay in a fair amount of time. We either have some cold/snow (my favorite part of the year here, best time for me outdoors unless it is icy, which isn't that often), some hilarious winds of spring in the land of sand, or scary hot temps for some of us. Well, October is usually nice.
I'm an old walker, around twenty miles a week, old jogger (never speedy but steady), old swimmer once I learned (eventually to a mile and kept that up for some years).
Now I stretch and dance (like the a2k music thread links).
I've never gotten into yoga, too much woowoo, I would have to asphyxiate the instructor, not a smart idea as the instructor would be stronger... as good as the basics undoubtedly are. I'd probably like t'ai chi and should look into it.
Being a garden designer, I've gardened for decades. Am not so interested in converting my present sand, a philosophic thing. I'm from California, as I keep bringing up; it's the place that Iowa revamped, the garden move that I stopped being part of quite a while ago.
