My introduction to Mick Foley was in Barry Blaustein's documentary "Beyond the Mat." Also known as "Cactus Jack" and "Mankind," Foley was a man who could take a LOT of punishment. He took a fall and the match ended when Foley became unconscious. In front of his wife and kids, Foley was repeated knocked upside the head with a chair. As The Rock continued his brutal act, Foley's son watched his father bleed.
Foley writes about these experiences in, "Foley is Good," his second book. While wrestling is still a part of his life's calling, Foley semiretired when he saw how this beating traumatized his family. http://www.wwe.com/superstars/raw/mickfoley/
