In some urban centers, workaholism is so common that people do not consider it unusual: They accept the lifestyle as normal. Government workers in Washington D.C, for example, frequently work sixty to seventy hours a week. They don’t do this because they have to; they do it because they want   to. Workaholism can be a serious problem. Because true workaholics would rather work than do anything else, they probably don’t know how to relax. Is workaholism always dangerous? Perhaps not. There are, certainly, people who work well under stress. Some studies show that many workaholies have great energy and interest in life. Their work is so pleasurable that they are actually very happy. For most workaholics, work and entertainment keep them busy and creative. Why do workaholics enjoy their jobs so much? There are several advantages to work. Of course, it provides people with paychecks, and this is important. But it offers more than financial security. It provides people with selfconfidence; they have a feeling of satisfaction when they’re produced a challenging piece of work and are able to say,“I made that.” Psychologists claim that work gives people an identity through participation in work, they get a sense of self and individualism. In addition, most jobs provide people with a socially acceptable way to meet others. Perhaps some people are compulsive about their work, but their addiction seems to be a safe-even an advantageous-one. 9.The passage indicates that workaholics          .
