Mike Tyson
At 20, Mike Tyson broke the record for being the youngest heavyweight boxing champ. By the time he was 25, Tyson was convicted of rape. He served three years in prison and later became heavyweight champ again; however, his career was marred by his infamous meltdown against Evander Holyfield. Tyson has found peace after boxing by becoming a vegan and recently headlining his one-man show, Undisputed Truth.
