There a tribe somewhere the members of which always know where north and south are. They achieved it through the way they orientate within the language. They don't say "behind you" or "on your left": they use absolute angular positioning to determine towards which end of the world the object is. Basically, their brain is being wired to orientate pole-wise from the very infancy.
