I feel guilty now, remembering that I asked you question no.5

Don't worry about it :-) That's by far the most common question, probably because most people (I understand) can't easily perceive how much of their sense of flavour is taste and how much is smell, so they're naturally curious about it. Unfortunately, I can't be of much help in answering that question, because I don't know exactly how much I'm lacking! What would be really interesting is to talk to someone who became anosmic after having been normally, er, osmic.

This might be partially modelled by an osmic person by a comparison of what things taste like when they have some form of nasal blockage (cold, hayfever, polyps etc) to when they don't.

See an episode of kitchen chemistry, in which professional taste testers had their nose blocked off (presumably to stop airflow through the nasal passage to the smell receptors). Blindfolded, and fed pureed food, they couldn't tell what the food was. They picked things at random based on the messages they got from their tongue.

Which I guess makes tongues Osmic Tentacles.
