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 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; that is, they might not enjoy movies, sports, or other

types of entertainment.Most of all, they hate to sit and do nothing.The lives of workaholics are usually stressful, and this tension and worry can cause health problems such as heart attacks or stomach ulcers.In addition, typical workaholics don't pay much attention to their

families.They spend little time with their children, and their marriages may end in divorce.

Is workaholism always dangerous? Perhaps not.There are, certainly, people who work well under stress.Some studies show that many workaholics have great energy and interest in life.Their work is so pleasurable that they are actually very happy.For most workaholics, work and entertainment are the same thing.Their jobs provide them with a challenge; this keeps them busy and creative.

Why do workaholics enjoy their jobs so much? There are several advantages to work.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 have produced a challenging piece of work and are able to say," I made that." Psychologists claim that work gives people an identity; by working, they get a sense of self and individualism.In addition, most jobs provide people with a socially acceptable way to meet others.
