The Oldest Water in the Known Universe:

Have you ever left a glass of water sitting out over night? If you have, then you know how this generally works out -- The next day, you get home after taking the dog for a brisk jog; you grab the glass of water sitting on the coffee table, and…bleh. Old water does not taste very good (okay, so it"s a rather specific scenario, but you get the point). And ultimately, this water has only been sitting around your house for a few hours. Imagine drinking water that has been floating about the cosmos for billions of years (not terribly yummy, I"m guessing).
