Thanks for that, I'm watching it at work. I remember reading some book about body language back when I was a teen, and the author stressed that the main things to look for are deviations from the norm for that person. According to them, you have to already be familiar with how that person holds and conducts themselves or you're just guessing. Which made sense to me at the time; I'm curious to see if that ancient memory will hold up against this video. Cheers!
