Average life expectancy in the UK has risen to 81, and the proportion of people who are elderly is growing faster in Wiltshire than almost anywhere else in the country, with a rapidly growing number of calls to 999 coming from over-75s. In Warminster, the emergency services are called to a crash involving three cars, which has left one victim with life-changing injuries. The 75-year-old man responsible for the accident suffered a suspected heart attack at the wheel. It is his second heart attack in seven months but all the police can do is advise him to give up driving. PC Phil Bridge says 'There's got to be thousands of elderly people who shouldn't be driving on the streets, that shouldn't have a license.
