I agree, each according to his own need.

In Baghdad the temp got up to 55 degrees Celsius, but the humidity was very low, usually below 30%. We had a regimen that included wearing 40 lbs of black cordura body armor, plus moderate aerobic activity at least 2 hours a day on average. In those conditions, 2 gallons of water goes through you pretty quick. The soldiers and marines consumed even more. It sounds extreme, but as long as you had enough liquids and minerals and stayed out of the direct sunlight, it was bearable. When we lost primary power and the backups failed, life got pretty miserable in those connex trailers/sweat boxes.
