If you're from a poor background, you have to work even harder. But that's what makes you who you are.

All I wanted to do was put together one of the best home maths systems in the world, and that's what we've done. I've loved numbers since I was two or three, and I get really excited about them. Now, I'm allowing myself to get excited about things. If you're doing it for a TV network or any major corporation, you have to put a lid on it a little.

My father was having an affair with a 16-year-old when Mum was pregnant with me. She found out when I was three weeks old and left, not surprisingly.

One day Mum saved up for this exciting new thing - a frozen chicken. She cooked it on the Sunday and we all sat around waiting for it, but there was a terrible smell from the kitchen. She didn't realise that the giblets were in a plastic bag inside it. We just ate vegetables and she cried and cried.

The first couple of days on the detox diet aren't pleasant.

Turning 50 changed me and I'm far more accepting of myself. I'm not thin, but I am a size 10. I go in at the middle and very much out at the bottom and top. And now I think, 'Well, that's how I am.

My bottom is so big it's got its own gravitational field.
