About sensitivity to odors: not only do I have a very weak sense of smell, but a lot of the few things that I can detect smell like alcohol to me.

There are big ethnic differences in apocrine sweat gland density and activity. Perhaps there are complementary ethnic differences in olfactory perception.

ethnic origin did not affect the results 
 
The participants ran the gamut of ethnicities from Ashkenazi to Sephardi to mixed. Not surprising. From the big recent selection papers, we know that genes involved in olfaction consistently show signals of recent selection, usually different across groups.

Smoking and age have no effect; I’d have lost a bet on that. One caveat: would smoking and age have been self-reported, or would they expect factual information?
