well for those 44 hours i was running around an army base camp doing orienteering and paintball stuff
i woulda kept going but the "game" "ended" at 43 ours and we spent an hour tracking back, i fell on my feet and got carried home lol
as far as just doing average stuff, i went through my entire HSC(well, HSC aint average, but it was hardly physically exhausting reading books and doing equations) without sleep=a week
