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

Change is one of my favourite words.

I loved doing 'Countdown.' I now consider that I was very, very lucky - not just because it was such a wonderful show to do, but because it lasted for so long.

I can't be bothered to go to the gym, though. I honestly just can't be bothered - it's the most boring thing on Earth. I have tried and every six months I go 'right, I'm going to the gym'. Then I do it for two weeks and get so bored by it.

For now I'm building up stories for the retirement home!

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.

I'm very pleased how my children have turned out.
