37 is a lumpy number, a bit like porridge. Six is very small and dark and cold, and whenever I was little trying to understand what sadness is I would imagine myself inside a number six and having that experience of cold and darkness. Similarly, number four is a shy number.

When I achieved the European record for reciting pi in 2004, this captured the imagination of Professor Simon Baron-Cohen in Cambridge and he finally diagnosed me with Asperger's that year.

No relationship is without its difficulties and this is certainly true when one or both of the persons involved has an autistic spectrum disorder. Even so, I believe what is truly essential to the success of any relationship is not so much compatibility, but love. When you love someone, virtually anything is possible.

I'm inconsistent because I'm human.

I'm not sure I'm the only savant with high IQ or with an above average IQ. Again, it may just be that we don't know very many of the others.

My algebra was relatively poor. I found it very difficult to use equations that substituted numbers - to which I had a synesthetic and emotional response - for letters, to which I had none. It was because of this that I decided not to continue math at Advanced level, but chose to study history, French and German instead.

I love music. I have a fondness for Chopin, and I very much like his 'Raindrop Prelude.'
