I feel badly for those girls who have to be so waif thin, doing those catwalks all the time because, luckily, we're going into a different time - that's what they're saying, at least - in we're appreciating a curvier figure. But to be honest, I couldn't be like an hourglass if I tried.

The thing about dancing - what it taught me all those years - is it gives you an amazing sense of discipline in forcing yourself to do things that you know are good for you but you don't really want to do.
