Sleep deprivation

Maybe we should all be sleeping

First, a few personal confessions: 1) I used to average five hours of sleep on weeknights, thinking this was a good thing; 2) I was once awakened by my air bag, after striking six cars; we were all very lucky this happened at a slow speed, while they were at a stoplight; 3) Ever since, for 13 years, I've used a sleep-apnea machine nightly.
