I answered with Bicycling, Gardening, and walking. But it never is as simple as that. I've ridden a bike constantly since I was 8. Had a paper route all through Jr and High School. I have really great legs.

Walking, well I was in Germany many years, and just loved the Volksmarches. Different area/town each week, walk 20km, around 12 miles. Check points, get card stamped, have a good german beer. At the end, a feast. yummy.

I grow a mean garden, hot peppers, tomatillas, and regular tomatoes. I grow peppers that make most men cry like little girls. I use them when I am cooking.
But it goes far deeper than that. I love to cook, I brew my own beer, make and bake my own bread. Cause I can, and I really enjoy doing so. I am learning to sew, I've bought a ton of patterns. I have three dolls by Annette Himstedt. Want to make clothes for them. I also have a my size Barbie, pathetic by comparason, but I have holiday clothes for her. She is wearing a wonderful Valentines dress right now. Uh, I have another doll, rather scary. Tiffany, you know, the Bride of Chucky! the other dolls don't get along very well with her.
Ok, so having dolls is a hobby too.
Oh, don't forget comics. Collecting comics is a great hobby. I have every issue of the Simpsons, but my favorite is the Japanese Manga, Oh My Goddess. I have one short box with nothing but that. I love the Japanese costumes, CosPlay. I would love to dress up like that, but there is no where to go, and you know our society just isn't ready for that.
Speaking of dressing up. And a bit of background thrown in. I am married, both of us were recently divorced after years of maraige and we get along purrfectly. Two kids, teenagers, came with the new marraige. I have always been interested in all things Midieval. So our whole family now dresses in 15th centure attire, and we go to events, and even walk through wallyworld in costume. Now that is fun!.
I built my first computer in 1980. I've built, upgraded, and done all sorts of things since then. Highly technical stuff. Photography, wood working, too many to mention.
Sorry, I ramble terribly. thanks for listening.
