We mistakenly assume that bodily survival has a higher precedence than ego survival. This is simply not generally true. Ego will happily destroy the body for its own sake. Look at overweight executives headed for heart attacks on the way to getting their pictures in Fortune or anorexic models suffering slow starvation on their way to getting their pictures in Vogue. Protecting ego is the general case.

I don't want any romantics to go into the military. I'm not a pacifist. I think we need a military, and the better one we have, the better off we are. I don't want kids going in there thinking that it's John Wayne on Iwo Jima. That's not healthy.
