So is this ability surprising though? As water is essential for surival, the ability to taste when water is 'off' would be a powerful evolutionary tool. This is maybe why water tastes 'like nothing' so we can better tell when there is something wrong with it.
- minitoar 6y agoI always sort of thought it was because we are mostly water.
- goldenkey 6y agoYeah, you would adapt to the taste. But what is the taste of saliva and mucous? I honestly don't know and now I'm curious if it highly varies.
- tomjohnneill 6y agoProvided you gain appropriate consent, there are definitely ways in which you can discover exactly how much the taste of these fluids vary from person to person.

- rcxdude 6y agoIt is pretty suprising!. There's no strong evolutionary reason for being able to taste the difference: there's no natural source of such concentrated D20 and it's only toxic if you ingest a lot of the concentrated stuff. It's not something any animal is going to encounter in nature. And by conventional chemical wisdom D20 and H20 are virtually identical: the electron structure is the same and that basically dictates the chemistry. The only significant difference is the mass of the molecule (about 10% heavier), and experiments with oxygen-18 water (which has the same mass as D20) showed it doesn't taste of anything, so it must be due to very slight changes in structure between the two.
