Television can gives us advantages and disadvantages increase our knowledge of the outside world; there are high-quality programs that help us understand many fields of study; science medicine, the arts, and so on. However,there are several serious disadvantages to television. Many children stare at a television screen for more hours each day than they do anything else, including studying and sleeping. It's clear that the tube has a powerful influence on their lives and that its influence is often negative.
Recent studies show that after only 30 second of television, a person's brain "relax" the same that it does just before the person falls asleep.
Another disadvantage is that television often causes people to become dissatisfied with their own lives. Real life does not seem as exciting to these people as the lives of actors on the screen. Also many people get upset or depressed when they can't solve problems in real life as quickly as television actors seem to. On the screen, actors solve serious problems in a half-hour program or a thirty-second commercial.
