When I used to ride horses regularly, and then not go for a while, I'd often have the smell of the stables lingering in my nostrils for days, even though we lived nowhere near the place.
Likewise, I once did a short work experience stint in the butchery department of a supermarket. I spent a lot of time pre-packing meat. Fine for a short time, but after three days the smell really gets up your nose. I was smelling it for weeks afterwards and couldn't stand the sight or smell of mince for months.
