An average man on an average day excretes two and a half quarts of sweat.

Not sodden enough for you? According to David A. Gershaw, Ph.D., “With people who are much more active, the heat and exertion can increase this output [output of sedentary person being a ‘small amount of fluid’ to 2 quarts per day] to 5-10 quarts.” Isn’t that how much fluid a car’s oil tank holds?

In case you were wondering, you can drink sweat.
