Mobiles and youngsters

BBC reported that 91% of the youngsters have mobile phones when they reach the secondary school in Scotland. The finding were reported by some survey group commissioned by The Carphone warehouse.

What could be the real disadvantages of this trend? Some days back there was this news where this teenager had some problem with her thumb and had to be submitted to the hospital. It was because of her excessive usage of text messaging. There should be more such health related issues attached if the mobile usage trend continue to grow in such way. I really think that no matter which direction the debate about radio waves affecting the brain cells goes, this trend would have some really bad consequences on the social health of the teenagers.
