We all know that Glenn Beck is a lover of history ... and on today's show, he sat down with Chris Stewart, author of 7 Tipping Points That Saved the World.


Beck calls Tipping Points a history book that everyone should own and read, because it "gives you some concept of how odd our life really is."


In this segment, Stewart discusses the reign of Genghis Khan, detailing how the emperor would kill his people and use their bodies as ramps in order to scale high walls in his kingdom, as well as use children as human shields while riding into battle.
