There was a woman recently who was nearly killed in the New York metro when she dropped her mobile onto the track. She climbed down to get it but if another passenger hadn't helped her,she may not have got up in time. A man was electrocuted charging his mobile phone whilst sat in the bath and the coroner is going to write to Apple suggesting they put a warning on the chargers,in case people are not aware of the dangers of using electrical equipment near water.
