Thanks for Sharing this, I have a special person in my life, at work. I have circular referenced him, asked the relevant question, conversed, and asked rephrased relevant question. Guess what - 2nd time Truth.... He is easy to spot, when it concerns a lie, he crosses his arm's - I always wondered if he knew how that made him look - like he is protecting himself. From what? When he is not, he tends to sit open looks relaxed and even may smile. I find body laguage to be a great indication of a person's mental state and I am not sure why they don't see it also? I really enjoy Ted Talk's (Truth) and thanks for sharing this one (Truth). I am 8 feet tall (lie). HE HE.
