I wish more people would make the distinction between tongue-taste and nose-taste if they aren't going to keep taste to sweet/sour/bitter/salty. I like to eat things with a strong tongue-taste, but a weak nose-taste, almost irrespective of the tastes.

So I like flavours like lemon, sugar, marmite, salty chips, and so on, and don't like strong cheese, most savoury tastes and so on. I even quite like the taste of Bitrex. I don't dislike smells, just eating things that smell strongly. I know that's completely different to not being able to smell, but it benefits from making the distinction.

I've never tasted it (because strangely enough they only seem to put it in Really Toxic Stuff), but I've always been curious to try it!

Usually it's shapoo or conditioner or soap (often stuff that smells nice). I'll shampoo my hair and accidentally leave a bit under a nail. And I chew my nails when I'm nervous and I'll think "ooh".
