In elementary school, sometimes our teachers would make us put our heads down on our desks. Sometimes it was punishment…okay it was always punishment even when it wasn’t meant to be because that is just not a natural position to maintain for more than a few minutes. Who thought of this bright idea? Did a teacher one day look out at her students, find them a bit sleepy looking and think, “Hey, if I force them to hunch over and put the bowling-ball-weight of their heads on a nice, hard desktop, my students will really thank me!”
