you have thus far drank nothing.(adsbygoogle = window.adsbygoogle || []).push({});

you have a 1 liter bottle of water(H2O),

you are now drinking,

and you have finished exactly 2/3 of the water(H2O),

now here is the triky part,

you piss 2/3 of a liter of piss back into the bottle,

now how much of the water content was lost through your body, AKA, what percent of the water bottle is piss and what percent of the water bottle is water.
