[Chalky] Wow. I, for one, have never heard of that. Out of curiosity, how accurately can you do this (exactly north, or just approximately?), and how rigorously has it been tested (not quite sure what the most rigorous test I can imagine would be -- maybe someone moving you while you were sleeping into a dark room where you have never been before?)? And can you point to any direction just as easily, or, if asked to point southwest, would you still start from north and work from there?

And do you have to be here to do it?

[Chalky] Can I carry you round with me next time I go orienteering?
I have a pretty good sense of direction and I hang around with a lot of very good navigators, but that's a first for me. I think we need a scan for an overdeveloped pineal gland.

I can always tell where I am and where North is -- I carry a street map and a compass whenever I travel.

[CdM] Just approximate north - nothing too exact! The other directions I would work out in a more conscious way.

[Dan] Interesting. Makes me wonder how bewildering I would find being placed on the north pole with nowhere to point.

[INJ] I don't think you'd want to be burdened with the load :-)
