There is a lot more to the idea of one having a 'sense of direction.' All animals, even humans, have some sort of a sense of direction. If you are my grandmother, it's weak, you may not be able to find your way out of a wet paper bag. If you are an avid outdoors person, your sense of direction is probably more developed and acute. Weak or strong, we all have a sense of direction. But where does that come from, and how does it work?
