Now you know.
When the news came out last month that scientists at the University of Toronto had discovered what might be the oldest water on Earth in a mine near Timmins, Ontario, the question on everyone's minds was what does a glass of the roughly 2.6-billion-year-old stuff taste like?
Since we can't try it ourselves, U of T scientist Barbara Sherwood Lollar has answered the question for you.
"It tastes terrible," she told the Los Angeles Times. "It is much saltier than seawater. You would definitely not want to drink this stuff."
Lollar said the older water is, the saltier it tastes. Her curious students are fresh out of luck, they're not allowed try it.
"If you're a geologist who works with rocks, you've probably licked a lot of rocks," she told CNN.
The find is exciting because it raises the possibility that life could also exist in tiny, ancient pockets of water trapped in rocks on other planets like Mars.
