David Grimstone was born in Margate on 25th January 1978. When he was a boy, he was often accused of daydreaming and `drifting off` during classes. He once let in five goals during a PE football match because he thought he`d seen a sparrow-hawk and went to investigate. The only two lessons he loved at school were English and History. David lives in Kent with his wife, Chiara, and their son Sebastian.
