  1.  @SilverAura  So many things about biology like that. The electrical action in a nerve happens across the nerve, not along it, and so the signal propagation along the nerve happens at sedate speeds on the order of 300 km/h (I think it might be slower for some nerves, like pain nerves). Another one: the raw light information picked up by your retinas is on the order of gigapixels. But there is no way your optic nerves can handle anything close to that bandwidth. So much of what you see is thrown away before it gets to your brain. And another one: your eyes continually saccade (move rapidly) from one viewpoint to another. This happens about once a second, and takes about a quarter second. But you never consciously see the world spinning around you: instead, one moment you are looking on one direction, next moment you are looking in another direction, with no memory of any viewpoint in-between. In other words, you are spending about a quarter of your waking hours effectively blind.

  3. What do you use to count them? A comptometer?
