Oh what *is* it about smells?? The memory of them is so powerful and so is the lingering in your nose. I can still remember, vividly, the only time I ever smelled gangrene.... I felt so sorry for the person who had it and was so isolated...I never got any better at coping with the smells and that's one of the main reasons I went off to specialise in the psychiatry side of things. I had a bottle of Chanel perfume (from a bloke I wasn't that keen on) that I used to drench my hanky every morning so I could breathe that in before going into the toxic zone. Strangely, I've never liked Chanel since!!! Poor guy; I feel guilty now!
