Sleep Better

Don't sleep with your smart phone nearby - CNN

Sieberg is hardly a guy stuck in some dust-covered, pre-technology past: He has always been among the first to own each new portable device, and he likes the many good things the digital experience can provide. But he realized -- when his wife would wake up in the middle of the night to see him, in bed, illuminated by the glow of one screen or another that he had decided to check one more time before he fell back asleep -- that something might need remedying.

There is, he said, a feeling common among people who are digitally hooked that, when it's just them and the real world and no screen, they are somehow cast adrift, cut off: "It's a sense of, 'What am I missing?'" But in truth, a strong case can be made that when a person lives too many hours a day in the digital universe, that is when he or she is really missing something -- missing the things that are taking place in the flesh-and-blood world.
