So...you're unconscious. That sucks for you, huh? After all, this is probably the result of being banged on the head, having some horrible illness, or just being so injured that you can't voluntarily wake up or move around. The doctors around you are talking openly about the likeliness of you never waking up. Bye-bye, you. But wait! You're not licked yet! As you slowly begin to rouse yourself, a telltale sign of your impending consciousness will show itself. It will often go unnoticed, perhaps when everyone has turned away. But it will indeed happen: your fingers will twitch back to life.
