Somebody has been watching way too much "Lie To Me"
As an expert on the matter all of this information is INCREDIBLY general and subjective. The fact of the matter is that Koveras is correct (I did not go to his link so it has nothing to do with the link). If you truly want to know when someone is doing something you have to watch them daily and know what they do and why they do it. Every person is different, and using general things like "everybody looks up and to the right when they lie" Then you're going to get things wrong 75% of the time.
