156. Olfactory fatigue - nobody can really smell themself very well

but I can guarantee that everybody has a smell - just ask a deer; they can smell you coming from a mile away.

Olfactory fatigue is the process that acclimates you to the smell of yourself and the surrounding environment, to the point that its no longer apparent to you. Typically, people within a given culture will have similar habits of diet and hygiene and will smell similarly, so they will all assume that none of them smell.

When people from two differing cultures come together, the first reaction of both may be "hmmf, what's that smell!"
