Do people use mobile phones too much?

I think we don`t have to use so much the mobile phone. There some studies wich say that sleeping with the mobile pone next to you, you can be very tired the next day because that has an efect on the brain.

Noeadays everybody has a mobile phone and some people think that it is a good or bad idea. I think the tecnology is important but the people use the phone for everything that they do, and I disagree about using the phone for all the things, but I agree to use the phone some hours a day but no9t all the time, for example to listen music, serching on the internet, takeing photos… I don’t really use my mobile phon efor all because I don’t need it.
