I am 56 years old (ouch), diabetic, and 40-50 lbs overweight. Besides losing weight, my real goal is to once again ride a bike! It's been at least 30 years since I've ridden one, (you never forget how, right??) I haven't told anyone, and I'm sure it's a stupid goal, but it's something I really want to do again. I'll probably lose the pounds, get on a bike, break my neck, and regain all the weight from the hospital IV's. Am I crazy, or what!?
