What does body language have to do with your score?

I learnt over 25 years ago from my mentor Anthony Robbins that our body language has an enormous influence on our emotions - how we move, how we stand, how we move our arms and legs. You could also say: show me how someone is sitting, standing or walking and I can tell what they are thinking and how they are feeling. In my first book "Never give up again - activate your perseverance gene", there is a chapter that deals with precisely this topic.
