Fittest On Earth: A Decade of Fitness documentary was a fun ride. I’m a sucker for watching the inspiration and insanity of this sport. We love to watch athlete Titans even if we know that we are watching them possibly destroying themselves. Football, MMA, Boxing, Rugby…etc, it’s madness from a certain angle but it’s a madness that’s hard to shake. There’s something deeply primal in our genes that still remembers the chase, the fight and the terror.
