VIDEO: Mike Tyson reveals the powerful, devastating impact of being bullied as a child

'Iron Mike' opens up on a subject that still affects him to this day.

Growing up in Brooklyn in the 1970s was not easy for Mike Tyson. He never knew his father and rarely saw the man, Jimmy Kirlpatrick, who dated his mother for several years. It may strike people as odd to think of anyone picking a fight with someone who would become the undisputed heavyweight champion of the world, but that is what happened to Tyson in his formative years. The retired boxer has opened up about the impact bullying had on him, saying it instilled in him a malevolent streak that resembles a cancer. The two-minute video, with GQ, is definitely worth the watch.
