The Puzzle of Anger and the Autonomic Nervous System

If there's no single autonomic nervous system fingerprint, so it's not the case that when you're angry, your heart is doing one always doing the same thing. And how is it that we're able to look at each other's faces and bodies and listen to each other's voices? So this is a really interesting puzzle. Sometimes in science, as you know, when you fail to replicate something or you fail to support a hypothesis, what is laid before you is the opportunity for great scientific discovery.
