When I was in grade eight, my school banned the Rubik's Cube. Why? Because some kid was wandering down the hall with his head buried in the Rubik's Cube, went headfirst into a door and split his nose open. The school's rationale was 'Well, we can't have kids walking around with their heads down.' Meanwhile, it was because we wandered around with our heads buried in our Rubik's Cubes that my generation can safely navigate through traffic on foot with our heads down while texting on our Blackberries. You could say it changed our lives.
