Dr John's practice covers 250 square miles of the North Yorkshire dales, and his patients are as likely to be a farmhand with a pitchfork in his foot as a baby with a cold. But he isn't just a GP. He and his wife Helen, a qualified nurse, race all over the dales in a specially equipped Range Rover attending accidents and saving lives. The money for the unit was raised by the local community at whose request this programme was made.
