Why is exercise important for people with diabetes?

It's important because the body is a machine. If we don't exercise it, then the body begins to break down. Firstly your bowels suffer.You get horribly constipated. Then your legs break down. They lose muscle tone.The attitude your mind has leads you to a depressing life.I am a diabetic, and I am 80 years old.Walking every day, and gentle exercise, plus brain work on my computer, keep me well
