Facts That Bother You (or Fun/Interesting Facts)

Sleeping

While you sleep, your body goes into paralysis.

This is believed to be so that as you sleep, you do not act out your dream, as you would with your thoughts while you're awake.

According to a Wikipedia article, "Glands begin to secrete a hormone that helps induce sleep and neurons send signals to the spinal cord which cause the body to relax and later become essentially paralyzed."

I hope you have fun when that guy outside your window comes in with a knife and you can't move... *shudders*
