When I was doing 'Generation Kill' in Africa I worked with five really super-trained Navy SEALs who taught us all these moves like how to disarm people: if there's a bar fight and someone's got a chair or there's someone with a gun behind our head, how to disable them and take them down in a swift move.

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.
