I liked this video. What Yaaron is telling is quite interesting. But looking at the faces of those young guys is also. How they are changing their minds. The one on the right seems, at first to just say "what the hell is that man saying, he is completelly wrong!". Then it is sometyhing more like "oh, wait, maybe I am wrong". Finally it turns to be like "Oh, maybe what I have been told until now was fully wrong! I should be researching more on it"

Thank you for sharing it, @rvanstel
