You sure it was a gallon? An American gallon is less than a British gallon IIRC.
IT was american gallon.
yeah probably while working out, this chick was drivin her car, not sweating/using anything in the water, just consuming it
and my friend drinks 8 bottles of water during school everyday, its just a matter of different people
well it was working out... Still I'm sure I could do a gallon sitting down.
