Why do people always want to play with their cell phones instead of reading books when they are bored?

A kind of nothing to do with people's spirit of support. Idle nothing to do, or lazy to do things, cut to play the phone does not need any technical content, there is no place to limit, you want to play, want to play how to play how to play, only have the network has electricity, want to play how long to play how long. For a long time, it has become a habit, it's okay to play with the phone, because do not play the phone do not know what to do. This is like children love to play with toys, the elderly love square dancing, nothing to do when they do nothing else but do these things.
