We're taught that we should get seven or eight hours a night, but lot of us sleep less than that, and some of us actually sleep too much. A study reported that people who routinely sleep more than eight hours a day and are still tired are nearly three times as likely to die of a stroke. Doctors have their own special sleep problems. Resident doctors（住院医生）are famously sleep deprived. When I was training to become a doctor, it was not unusual to work 40 hours on end without rest. Most of us took it calmly, confident that we could still deliver the highest quality of medical care. Maybe we shouldn't have been so sure of ourselves. An article in the Journal of the American Medical Association points out that in the morning after 24 hours of sleeplessness, a person's motor performance is comparable to that of someone who is legally drunken. Curiously, doctors, who believe that operating under the influence of drinking is grounds for dismissal, often don't think twice about operating without enough sleep. "I could tell you a horror story," says Jaya Agrawal, president of the American Medical Student Association. "A doctor was operating after being up for over 36 hours, and he almost fell asleep standing up and nearly face planted into the wound.” Agrawal's organization is supporting the Patient and Physician Safety and Protection Act of 2001, introduced last November. Its key provisions include an 80-hour workweek and a 24-hour work-shift limit. Most doctors, however, resist such interference. Dr. Charles Binkley, a senior surgery resident at the University of Michigan, agrees that something needs to be done but believes doctors should be bound by their conscience, not by the government. The U.S. controls the hours of pilots and truck drivers. But until such a system is in place for doctors, patients are on their own.
