Excuse my ignorance, but don't we also produce a significant amount of H20
metabolically?  My recollection of high school biology is a bit hazy, but
I thought the basic metabolic cycle was oxidation of e.g. sugars into
water plus carbon dioxide, and of more complex organic compounds containing
carbon, oxygen, hydrogen and nitrogen (e.g. proteins) into carbon dioxide,
water, and urea (to get rid of the nitrogen.)

Please, no flames.
