It's said that young people are the most nomophobic group, and it should be true, but there is a wide range of people which is addicted to electronic devices like mobile phones.
Firstly, mobiles are really useful. In fact, the have been porbably the most important discovery for several years ago. It's very easy to understand, mobile phones are even faster and more functional than computers, furthermore they can call, take and share photos quickly, they have alarm and hundreds of applications... That's why a lot of people use it daily. It's also said that children soak up information like a sponge. For these reasons we "need" it and in some cases, too much.
But, in my opinion, every new discovered stuff needs a testing period in order to find out all the challenges it can drive. Nowadays we are in the mobile phone's testing time and, so far, we are using it too much. We must try to control this addiction and be aware of the devices' radiation.
All in all, mobile phones are so interesting and useful but we must watch closely its adiction and its possible problems.
