Did You Know?
If you lie on the floor with your head scrunched against a little seat (in order to be in the room with the most A/C) and read for an extended period of time, then the back of your head and your neck can lose circulation and "fall asleep" -- I've had my arms, legs, and butt fall asleep, of course, but I never had this region fall asleep until yesterday, and it felt mildly psychedelic when the rear portion of my skull suffered the dreaded "pins and needles."
