A scientists takes a sample of water from a mine deep underground in Ontario, Canada. The water turned out to be 2.6 billion years old, the oldest known water on Earth. Credit: B. Sherwood Lollar et al. Last month, scientists announced they had found an ancient pocket of water buried in a mine 2 miles below Earth's surface. The water, up to 2.6 billion years old, may have been around longer even than multicellular life. The find raises intriguing possibilities for understanding how life arose on Earth and if it could survive on other planets. But the really burning questions is, of course, what does it taste like?
A: all water is excreted.if you drink for example ''100 units''60 will go when one urinates10 will go by sweating30 units will go into cells, and 30 will come out again and get excreted for example instools (feces) respiration (breathing)eventually all water is excreted (within about 48 hours) so water needs to be replaced constantly because we're going to lose water even if we do not drink it - thats why people dies after 48 - 72 hours of not drinking. hope that helps you
