Health Update: Nail-biting survey

DOCTORS at Bristol Royal Infirmary have been investigating nail-biting. They sent a questionnaire to nearly 2,000 people between the ages of 25 and 69. The survey revealed that more than a quarter of the population in their twenties and thirties chew regularly. This gradually drops to 10 per cent in the older age groups, according to a report in the Journal of the Royal Society of Medicine.
