I would have placed the below link in Sociology but USMB lacks a header for that field. The below link DOES include the Big Three; Sociology, Psychology & Philosophy plus Political Science in practical use regarding past, present & FUTURE GLOBAL SOCIETY. I noticed the author has in tow well over a half million subscribers & the comments are very positive regarding vid/author in general. The vid is close to an hour in length but moves @ a pace that is both comfortable but fast enough to ward of any boredom.
