> Failure is costly and things like accelerated aging and burnout are real. I can attest to the flipside of this argument - I am 39, for whatever reason have never overstressed or overexerted (took a relatively easy career, don't have a family etc.) and I, even with much less than perfect lifestyle habits, probably look 10 years younger than many people my age. I wonder how much of it is just genetics (plus not liking to be out in the sun) and how much is the life choices.
