mireckca - How do you like it up there in Toronto? How is your foot doing? When was your surgery? I can understand how physical limitations could restrict your ability to be more active. It sounds like walking isn't exactly a small task for you. I guess as humans, we don't realize what we take for granted until/unless it's not there anymore.
Steph - Toronto is great. It is really the financial and business center for Canada, so it's been a comfortable place to be for me. I worked in NYC for 12 years before coming here - so it's nice being in a cosmopolitan place without alot of the headaches that Manhattan has. Of course, everytime I get home to NY I hate to leave it again.
My foot operation was about 10 years ago and it doesn't impair my mobility now. I walk probably 10-15 miles per week just doing errands and going about town. But the next day I do pay for it in my knees - old childhood, sports related injuries, I think. So I stick to low-impact, elliptical types of exercise whenever I can.
All the best to you as you complete your program. This is a good place to take a break and maybe even have a laugh or two.
