It's an inefficient allocation, in my view. I consider exercise (and a few other things) to be necessary to sustainably perform at a certain level. I don't see them as merely enriching things, but necessary things in order to maintain my spirit (body, mind, and soul). In the vein, they gain priority over everything else. If life comes to a point where I have to sacrifice the things that keep me going (say for instance sleep, food, sunlight, and social interaction; for you it might be family), then I must figure out how to get rid of the other "balls" ASAP with the least amount of cost. And once that's taken care of, were they really that important if they're so easily disposed of? If you lose your spirit, or let it wither by a thousand cuts a la burnout, what do you have left?
