     A new generation addiction is quickly spreading all over the world. Weboholism, a twentieth century

disease, affects people from different ages. They surf the Net, use email and speak in chat rooms. They

spend many hours on the computer, and it becomes a compulsive habit. They cannot stop, and it affects

their lives. Decades ago, no one thought that using computers could become compulsive behavior that

could affect the social and physical life of computer users. This obsessional behavior has affected

teenagers and college students. They are likely to log on computers and spend long hours at different

websites.

     They become hooked on computers and gradually their social and school life is affected by this

situation. They spend all free time surfing and don't concentrated on homework, so this addiction

influences their grades and success at school. Because they can find everything on the websites, they

hang out there. Moreover, this addiction to websites influences their social life.

     They spend more time in front of computers than with their friends. The relation with their friends

changes. The virtual life becomes more important than their real life. They have a new language that

they speak in the chat rooms and it causes cultural changes in society.

     Because of the change in their behavior, they begin to isolate themselves from the society and live

with their virtual friends. They share their emotions and feelings with friends who they have never met

in their life. Although they feel confident on the computer, they are not confident with real live friends

they have known all their life. It is a problem for the future. This addictive behavior is beginning to affect

the entire world.
