@strawCake - I agree. And I think the anatomical position at least makes logical sense. Most of us consider the head to be the "top" of the body as it is on the anatomical position.
The only thing that doesn't make sense is that the thumbs are facing away from the body. I don't know about you, but I don't naturally stand with my palms facing forwards. I guess at some point they had to decide on a hand position and go with it though.
