...wave sleep. Intriguingly, humans spend much more time in slow-wave sleep during the first three hours of the night than they do in the hours just before waking. Children are champion slow-wave sleepers, which is why they sleep so soundly when being carried from the car to bed. Adults, on the other hand, get less and less slow-wave sleep as they age, which may be one of the reasons they wake up more often in the night...

The staff trained a video camera on me and fitted me with a brace to measure my chest movement. Then I was told to relax and fall asleep. Yeah, right. Eventually I did. And then halfway through the night, a nurse came in and put a special mask on my face. It looks like a respirator, which is what it is. The CPAP (an acronym for continuous positive airway pressure) machine...
