Born to Rage: Inside the Warrior Gene
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.
