I'm probably the most negative person around.

I think I've achieved everything I wanted to.

Back in my mind, I never, ever wanted to give up swimming; it was something that I would carry on with.

I've been lucky enough to travel the world and win awards and medals, but it was time to stop.

It is wonderful to say that your days behind a school desk are over. It's just another phase in your life.

By 9:30 at night, I go to bed.
