	Impure water, mostly.

	People in general require about 2 qts..1 gallon of water a day
(and those of you who want to argue -- count up the number of coffes,
teas, and sodas you consume; if it still is less than 2 qts (8 cups,
a little under 2 litres) then go drink something, for ghodsakes.)
That comes out to be 2-4 kilos a day right there.  I also recall (this
isn't certain, but not a bad ROM I'm sure) that people require about
1.5 to 2.0 kilos of oxygen a day.  So that makes up the required 3 kilo
a week nicely.

	Remember, it says ``average molecule'' -- I'm sure that some
molecules don't turn over in anything like that length of time.
