National Geographic Explorer Season 6 Episode 20 Born to Rage?

Were you born to rage? Is the need for anger management in your genes? Many, like ex-punk rocker Henry Rollins, have struggled with feelings of aggression their entire lives, and National Geographic is on a mission to figure out why. Scientists are investigating a single gene-dubbed the warrior gene-that has been associated with violent behavior, raising the disturbing possibility that some people are Born to Rage. Henry tests this theory on a colorful crew: outlaw bikers, mixed martial arts fighters, Buddhist monks and former gang members. DNA testing reveals which of them-including possibly Henry Rollins himself-carries the warrior gene. The results provide an extraordinary insight into human behavior.
