The advent of the cell phone leads to change less conversation among people, for example among family, among friends.
Besides there is nearly time to stay alone. Anytime people call or send message to me and then I have to speak something, although I don't want to.
Thesedays smart phone prevents from reading books or newspapers. People watch vedio on internet or news on internet through their smart phone instead of reading books or newspapers.
I think people need to stay for only few days free from cell phone.
