I think the sad thing is that people take this to mean, "block off more time to sleep" when much, much more common is the issue that we're in civilized society. Most of us have some level of reduced oxygen supply during sleep and exposure to allergens (especially in kids who go to public school). I suspect that most people who pass the fuck out at 12am, sleep like a brick, and wake up groggy at 6am will naturally want more sleep the next night. The real issue comes when people are hardly sleeping at all no matter how much or how little effort they devote to their new self improvement plan.
