I think what suf is also trying to say, and I agree with, is that one can be perfectly healthy and not exercise. Well to the extent some do, anyway. There is an adequate health level and anything more than that is just extra work to be honest. I'm not trying to discourage working out, but really no one needs an excuse for why they don't. Now maybe you could ask why you don't eat healthy, and I could tell you that I can only afford the cheap, nuked meals, or I don't know how to choose healthy foods, or I hate myself anyway, etc.
