I think when someone has cancer, a slight health improvement is big enough. Furthermore, people experiment with all kinds of things for slight health improvements to stay healthy. Working out is not the most pleasant experience when you think about it, but it becomes pleasant because you mentally associate it with something positive and there are traces of euphoria kicking in when it's a pretty intense workout. Most people work out to lose weight when it's been years I've told anyone who asked me that for weight loss, working out is more tiring and less effective "calorifically" than simply not eating that extra piece of pie. I've seen people want to lose weight, go for a 20 minute run, then come back and down all kinds of food and still hoping/believing/thinking they're going in the right direction for weight loss and they're eating to recover from the effort. An Olympic swimmer might need 4,000 calories daily. Most of us don't.
