Mobile Fever
Why are we so addicted to mobile phones? There are now over forty million people in
Britain with mobiles and if the present trend continues, every man, woman and child in Britain will
soon have one – or two, or three!
They can be expensive and are possibly bad for us. You can spend a lot of money if you use
your mobile a lot. According to some scientists, if we go on using mobiles, we’ll cook our brains.
Some people even say that radiation from mobiles causes cancer.
Teenagers are among the biggest users of mobiles, and ‘texting’ is creating a new language
full of abbreviations such as ‘How RU?’ in Japan, Surveys show teenagers are reading less and
mobile use is affecting the marks of secondary school learners. A big problem in Britain is crime.
Last year half a million British teenagers were victims of mobile phone theft.
