I am super sensitive to any smells, but I don't mind many of the things that whip up a frenzy in groups of other people. I can smell who came to the house during the day, many times. Noxious chemicals, like used in photography or plating and imitation scents or flavorings do annoy me.
I seem to have not only a high sensitivity and can smell yuck a mile away, but also I have a high tolerance to things that make others hurl. I'm sometimes the only one who can handle cleaning up nasty stuff, like a liquified dog that died under my neighbor's porch.
