In The Book of General Ignorance, John Lloyd and John Mitchinson say that some Eskimos**** have same word for 'smell' and 'kiss'.
And 'In some tribal cultures the "equivalent for our 'kiss me' is 'smell me.'' Wikipedia, Kiss
I just love that!
And further. But there have been already many online talks about pheromones, smell and love so I won't bring this again. (a short report on some scientific research here)
****I use the word Eskimos to name the 'indigenous peoples who have traditionally inhabited the circumpolar region from eastern Siberia (Russia), across Alaska (United States), Canada, and Greenland.' There is no pejorative conotations. I know that in North America is preffered instead Inuit. Specifically, Inuits are only a group of the Eskimos population, so I chose to use Eskimos since I do not have clear knowledge of what group of Eskimo use same word for smell and kiss.
