"I can’t think of a【C1】______study that hasn’t found Americans getting less sleep than they ought to," says Dr. David.【C2】______people who think they are sleeping enough would probably be【C3】______off with more rest.
The beginning of our sleep-deficit crisis can be 【C4】______to the invention of the light bulb a century ago.

By the 1950s and 1960s, that sleep schedule had been reduced【C8】______to between 7.5 and 8 hours, and most people had to wake to an alarm clock. "People cheat on their sleep, and they don’t【C9】______they’re doing it," says Dr. David. "They think they’re okay because they can get【C10】______on 6.5 hours, when they really need 7.5, 8 or even【C11】______to feel ideally vigorous."

To assess the【C17】______of sleep deficit, researchers have put subjects【C18】______a set of psychological and performance tests requiring them, for instance, to add columns of numbers or recall a passage read to them only minutes earlier. "We’ve found that if you’re sleep-deprived, performance【C19】______." says Dr. David. "Short-term memory is impaired,【C20】______are abilities to make decisions and to concentrate." [br] 【C2】
