I've never thought of exercise as a way of prolonging life. I think modern medicine does a better job of that then me running 25 miles a week will ever do. Quality of life? I think exercise helps a lot with that. If nothing else it's a pleasurable experience on it's own terms. It's pleasing at the moment and in looking forward to or back on the time you've put in. It improves the quality of your life when you're not engaged as much as when you are.
