Oh that was absolutely fascinating!* The cardinal directions
  thing was quite mindblowing to me.* I had always wondered, "Why
  can't we just refer to things by their REAL direction?"** I find
  I can't always tell you what street I'm on [I'm terrible with
  street navigation] yet I always know whether I'm traveling
  north, south, east or west and which direction home is, because
  I have a dreadful fear of getting lost... and I know that, if I
  know the cardinal direction where home is... I can always get
  there, eventually, even if I have to traverse a number of
  strange roads. I can't do what they do.... but I'd be curious to
  try now.* I probably learned cardinal directions from Boy Scouts
  and it sunk in for me - right now, I'm facing West - my house is
  north of me - I'm on the porch that's on the south side of the
  house.* In my mind, I know the trajectory of the sun, and I
  always seek out the north side of buildings, because I like to
  know where the shady spots are when I get out of the car. Yet, I
  have trouble with my left and right.* Always did. Hm. I will
  look more into these people.* I found an article that questioned
  just how lacking their sense of relative direction is;
  apparently they used hand-gestures to combine their sense of
  relative space along with their absolute cardinal sense; which
  makes a little more sense to me.* It means they are more aware
  of their territory in terms of quandrants than we are, but they
  do use a local frame of reference as well, but only as much as
  they need to get the listener from where they are at present to
  mentally envision the "over there".* In short, they can handle
  relative and absolute positioning simultaneously, something we
  would have more trouble with. Still, quite fascinating and I
  will read up more on these people.* I enjoy embodied cognition
  viewpoints; it's at an early stage, compared to computational
  theories of mind and such, but it has great potential to expand
  our way of looking at the world.
