I've always had an odd pleasure at standing at the edge of cliffs. Something meditative about trying to overcome the feeling of unbalance. Think about it, you can be perfectly balanced standing on a cubic foot of rock. But if it's suspended hundreds of feet in the air, you would feel unbalanced (wind notwithstanding).

It turns out that this actually is dangerous. The feeling of imbalance is a "real" reaction your body has.
