Drunk only nine times?
The amount of fresh water on the planet is constant. The water we have now is the same water that we had when dinosaurs (or Adam and Eve, if any of our R&S ABers read this thread) were drinking and weeping the water. I'm guessing that all the fresh water on the planet has been drunk and wee'd thousands of times, absorbed back into the soil, popped up out of springs, bottled or collected, cleaned, filtered, and then given back to us so that we can, basically, drink dinosaur wee.
And THAT is why you should only drink wine and vodka.
