I'm not a big believer that attitude alone can heal the body, but it can have a very large impact on what you do, which in turn can have a lot to do with how well you do with the disease. After my surgery, on days when I was thinking about riding my bike, but not feeling all that great, I reminded myself that I was fighting my way back to health, and there isn't much better therapy for lungs than riding a bike. And bike riding is a funny thing, in that there will be days when you don't feel much like riding when you start out, but you'll almost always be enjoying yourself after just a short distance of riding. It takes the attitude to get started sometimes, though.
