I wanted to mention the beauty of team spirit shown by Nash and his team mates. Lions also work together intelligently, as do wolves and killer whales, but it is to kill. People work together, but may customarily downplay their sense of camaraderie, except when overtly playing it up for obvious social reasons. But when you see these dogs work together, it is not to kill, and not to pose for cameras. No, they show a purity of team spirit in a unique way that I can't help but admire.
