I have a very acute sense of smell when it comes to analysis. In the kitchen, for example, my nose is a finely tuned, olfactory machine. I can identify constituent components of sauces, or distinguish wine varietals with a fair degree of precision.
But when it comes to environmental factors, my filters often get in the way. I can't count the number of times my partner has come home to exclaim, "what's that smell?" when I have noticed nothing.
