Sorry, my water estimate of 1/2L to 2L per hour is correct for _outside labor_(pitching big tents, digging holes, carrying a forty kilo rucksack) in an arctic to sub desert climate. 2L per day is a good estimate for working in an office/walking around shopping <img src="/images/graemlins/smile.gif" alt="" /> Most of uswould probably feel bloated only drinking one liter per day in a sedentary environment.
