William Fernando Souza Bezerra (born 20 September 1984) is a Brazilian cruiserweight professional boxer. Bazerra is the current South American cruiserweight champion and a former Brazilian, WBC Mundo Hispano, WBA Fedelatin and WBA Fedebol cruiserweight champion. Using only the above description and what you know about the world, "William trained to be a boxer from a young age." is definitely correct, incorrect, or inconclusive?
