What I've found I really like about sci-fi is it can look at philosophical questions about humanity but in a different context. It can really make you think. That's what 'Doctor Who' does, even if it's a bit silly some other times.

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.
