RECENT announcements that there is to be an investigation into the intensity of use of mobile phones, directed especially towards adolescents, comes as no surprise.

The impending health problems, such as hearing and sight problems, including many hours spent with computers, could well affect the NHS for generations to come.

Have we reached almost saturation point when no one person regardless of age, faces the prospect of venturing away from home without their mobile phone? It is almost a necessity, leaving the written word resigned to history.

One has to realise that mobiles serve a useful purpose in times of emergency situations, but there is a time and place for everything, and not at the expense of someone's long-term health or educational progress. Everything in moderation.
