If David is trying to remember facts he also links them to an image. 'For instance,if i was trying to memorize the name 'Tom Cruise',I would think of his film Top Gun, and that leads me to images of guns and cruise missiles. If I was trying to remember a place name,for instance 'Quito',the capital of Ecuador,i might think of a 'key to' open a door.'
You might wonder what the point is of being able to remember 22,500 number. But David is soon going to appear on TV's Record Breakers,and this week he is teaching memory training and speed-writing at Huddlesfield University. His fees are 600 a day. He is sure that the future holds a lot more for him than a jop as a fire-fighter.
