Mind manipulation by Keith Barry at TEDx

I think the TEDx concept needs no introduction (if you want to know more, you can read about it here). It is essentially a conference where lectures and speeches are given by people involved in science who simply have something significant to say. This time, the speaker was Keith Barry, a man recognized as a mentalist, an expert in human behavior, and a master of reading body language. I have written about him before when discussing manipulation. Below, I am sharing his TEDx presentation.
