I have found the quality of the video very good and the subject matter very interesting and well presented. I really enjoy learning the science behind what I have sort of “known” most of my life. It really all makes a lot of sense and there have already been several “AH HA” moments where I go “I knew that” but at the same time could never explain why to anyone.
