Is it true that some people never smell?

Hey! Maybe a bit of an odd question, but I have read recently about people that never use deodorant because they simply don’t need it. Does this have anything to do with genetics?

Yes, this is true and yes, this has everything to do with genetics.
Around two percent of the world’s population carry an unusual form of a specific gene (ABCC11) that means their armpits never smell and therefore they never have to worry about wearing deodorant.
