...months, we crisscrossed the country, interviewing sleep experts, getting tested in sleep labs and even flying a 747 simulator after being awake for 30 hours. I got my first clue that I might be more sleep deprived than I thought in a lab run by Robert Stickgold, a cognitive neuroscientist at Harvard Medical School...

Yet 71% of American adults and 85% of teens do not get the suggested amount, to the detriment of body and mind. "Sleep is sort of like food," says Robert Stickgold, a cognitive neuroscientist at Harvard Medical School. But, he adds, there's one important difference: "You can be quite starved and still alive, and I think we appreciate how horrible that must be. But many of us live on the edge of sleep starvation and just accept...
...that changed once scientists knew which kind of memory to study. Over the past couple of years, Stickgold has teamed up with Matthew Walker at Boston's Beth Israel Deaconess Medical Center to investigate sleep's effects on procedural memory for motor skills.
