Secrets To Body Language VID

I think that the video of the "Secrets Of Body Language" is a very helpful video. It is because now, for example, if I'm talking with someone, I'll know what he/she feels about me by looking at what they do with their body. I also think that some parts of the video is wrong because the part when the video says that, "crossing arms mean that the person is trying to hide something," is wrong. Sometimes when a person is crossing arms meant that the person is saying. So I think that the video is good, but few parts are wrong.
