Could be a resource?

To add: a person 10000 of miles away will still express on his face the way a chef will. Disgust=disgust. Lust=lust. I'm talking faces and not body language

My understanding is that nearly all body language reading techniques are pseudoscience, and even though there have been studies on it there have been no successful practical applications.

He's also charging a lot of money for this content, so I wouldn't consider it a worthwhile resource.
