Thank you, Majad!
I try to become better at using (relevant) body language. Not the random hand formations some people use - President Obama is a good example of this. He moves his hands a lot when talking, but the hand formations doesn't really mean anything. I am trying to become better at using body language to graphically illustrate what I'm talking about. The moving eyebrows is probably a result of my mind focusing a lot on body language. I'm rarely aware that I do it, but I guess doing things with my eyebrows is a way to enhance, a way to make people more interested and focused. ...which is what people like President Obama do to, primarily with their hands; their body language doesn't mean anything on its own, but it enhances. So I guess I am a bit like them, but on the other hand, I bet that if I could graphically illustrate things with my eyebrows, I also would.
