Born on a blue day - Daniel Tammet

Daniel sees numbers as shapes, colours and textures and can perform extraordinary maths in his head. He can also learn to speak a language fluently from scratch in a week. He has Savant Syndrome, an extremely rare form of Asperger's that gives him almost unimaginable mental powers, much like the Rain Man portrayed by Dustin Hoffman.

Daniel has a compulsive need for order and routine - he eats exactly 45 grams of porridge for breakfast and cannot leave the house without counting the number of items of clothing he's wearing. If he gets stressed or unhappy he closes his eyes and counts. But in some ways Daniel is not at all like the Rain Man. He is virtually unique amongst people who have severe autistic disorders in being capable of living a fully independent life. It is his incredible self-awareness and ability to communicate what it feels like to live in a unique way that makes his story so powerful.

Touching as well as fascinating, Born On A Blue Day explores what it's like to be special and in so doing gives us an insight into what makes us all human - our minds.
