I've always liked to think I could do anything I wished as well as - if not better than - a man. But I wasn't very good at rally driving.

When you have children your house smells very unpleasant all the time.

Even when I wasn't overweight I was never one of those girls or women who wanted to look nice. I always thought it wasn't important.

What could be funnier than a fat person trying to run a marathon?

The problem with comedy audiences - it's like the Coliseum - when they see someone struggling, they don't feel altruistic towards them. They feel slightly repulsed by it.

I'm just trying to spread the word and upturn the myth that actually you should be resting after cancer treatment. You shouldn't; you should be getting out and doing any kind of exercise you can. You don't have to run a marathon, but you just have to up your activity levels.

If you're a fat person - and especially if you're a woman - at all stages of your life you'll get abuse for it, so you have to work out a way of dealing with it. The best way is to be humorous about it - that defuses any tension.
