Interesting video. It's good to learn about this body language analysis. It's highly possible that Jermaine has had a media training including a body language training. He knows how to express in front of the camera and not to reveal too much and yet to give an open and sincere impression. He knows exactly how to answer difficult questions without giving a solid yes or no, yet seemingly a satisfying answer to the interviewer.
I'm definately going to watch the body language analysis of Conrad Murray, of which he was promoting
Though, I expect the same about Murray. I'm pretty sure he has had a media training as well in order to not to reveal too much.
