I used to do push-ups on my knuckles on gravel and other asceticism of the body practices to harden up my mind and body, pushing my limits, and all that. Now I realized it's futile and drink a lot of beer, watch tv and browse the internet all the time and avoid all kind of physical efforts when possible. Actually my most physically challenging activity is solving chess puzzles on diagrams. What can I say, I'm lazy? Survival is about energy conservation anyway. Once you have bugged out, you have to shelter-in-place for a long period of time and my mind is ready for that.
