David Thomas struggled at school and got very few exams. He joined the Fire Service aged 20 but kept badly failing his promotion exams. At the age of 28, he bought a book on memory improvement to help him after seeing a guy on TV memorise a pack of playing cards. Just 8 months later, he went to the 1996 World Memory Championships and came 4th. He has since gone on to develop one of the most powerful memories in history.
