World's oldest water? Samples may date back 2.5b years

Story here

Deep in a mine in Canada, scientists have found some very old water. You may not want to sip any just yet: it's two and a half billion years old.

From the article:

As well as the new estimates for the volume of the ancient water, the researchers used data from 19 different mine sites, studied as part of the Deep Carbon Observatory programme, to assess how much hydrogen was being produced through the underground chemical reactions.

But what they're saying is, this water hasn't been to the surface, or hasn't been contaminated by surface water, for at least that long.

Pretty neat to think, though - 77% of your body mass is actually older than the planet you're standing on.

So is the other 33%, though, so.
