In addition, cell phones lead to addiction. I have a friend who suffers from chatting addiction and that`s because she spends most of her time chatting wih her friends on Facebook or Yahoo massenger programm.I remember that during one of our criticism lectures, she asked me to give her my mobile because she wanted to log into Facebook to chat with a friend which was very strange for me especially we were in a lecture.Moreover, cell phones cause a nother kind of addiction which is sending messages addiction, I remember a woman in Opera Winfrey Show who sends messages even in the bathroom, and sleeps with the mobile in her hands.This woman nearly sends about three hundreds messages monthly or more.
