I can recognize anyone from smell?

Whenever i talk to somone or be in close proximity I they have a distinctive smell, that is not their perfume or deodrant, oh I can smell that too but it is smell that is always with them, its so strong that I can detect someone with my eyes shut by just smelling, most people have a buttery kind of smell, some people a diluted strawberry, gone off vegtable kind of smell, some smell like asparagus, even a hint of lemony and soil I know this is weird but serioulsy its true Iv got a gift anyone else have this?
