Abstract
If I ask you what is the thing that you always have with you? You will probably answer: "my watch", "my purse" or "my diary"…but I am sure a lot of you will answer "my mobile phone"!! and it is normal, in fact, if you think well, this little device can replace all the things quoted before: you can use it as a diary, as a watch, you can play with it when you are in public transports, you can take photographs, you will probably in few years be able to pay with it and we don't have to forget it, you can use it to call someone!! In short, everything is done on it so that you couldn't live without your mobile phone. It is a fact, that nowadays, we need it, and it is the case of 40 million users (against 35 million for classic phones that can give you an idea of the importance taken by this phenomenon in our society)So it is a very common and useful object but what about our health? We have all heard about the bad effect that could be entailed by “our most faithful companion”, so what can we say today about that?
