> they should be familiar enough with the concept of long term wear and tear to draw their own conclusions about what's appropriate. From ages ~15-22, I averaged less than 6 hours of sleep a night, ate north of 4000 calories of junk food a day yet had visible ab muscles with minimal exercise, could stay up ~36hrs before I'd have to crash if I needed to, all but the worst cuts, scrapes, and bruises healed completely and disappeared without leaving a mark in 12-48hrs, I simply did not get hangovers ever, could push myself to run a pretty damn fast mile despite not being a runner and not feel it at all the next day, and so on. I don't think I had a very good handle on what long-term wear and tear was like except in a very abstract way.
