Here's a good one on body language. In primatology a baby being fed and quite satiated will reject the offer of more milk or baby food with a brisk movement of the head to the side. To say NO without words one shakes the head back and forth.

Interestingly, and I never saw anything like it, when good-boy VP Pence speaks he often shakes his head negatively even if what he's saying is positive. It's like a body language sign saying “Don't believe this bullshit.” Amazing. Next time you see this Prince of the Church on TV see if what I'm saying isn't spot on.
