I was so excited when I got my first mobile phone - I could make calls anywhere! But now that I use my mobile for so much more, I worry that I use it too much.
Researchers theorise that the developing brains of children may be more susceptible to over-use of mobile phones. They will investigate this by tracking the mobile usage and cognitive development of 2500 children aged 11 to 12.
Whatever the results, I think we should all cut down on our mobile phone use and enjoy what's around us more.
