Former world heavyweight boxing champion Mike Tyson will make his first appearance in Hong Kong next month to talk about his legendary life. The 46-year-old American has been invited by a brokerage and investment company to discuss his life before, during and after boxing. He will also talk about his time in juvenile detention and prison, his faith, his sobriety, his family and his acting career at a luncheon meeting on September 12. A spokeswoman for CSLA Asia-Pacific Markets, which has organised the event exclusively for its clients, said Tyson was a remarkable person who could offer a "unique and memorable" experience to the audience. With nicknames such as "Iron Mike" and "The Baddest Man on the Planet", Tyson holds the record as the youngest boxer to win the World Boxing Council, World Boxing Association and International Boxing Federation heavyweight titles. He has also been inducted into the Boxing Hall of Fame. Despite his success in sports, New York-born Tyson's private life is still controversial with three marriages, eight children, the loss of a US$400 million fortune, bankruptcy and battles with drugs and alcohol. A rape conviction 20 years ago led to three years in jail. "I wasn't a good person then," he told London's Financial Times. "I was raging and mad and angry." Tyson has recently been showing off his talents outside the boxing ring, taking to the stage with a one-man show entitled Mike Tyson: Undisputed Truth . After a successful run at the MGM Grand's Hollywood Theatre, the show opened on Broadway under director Spike Lee at the end of last month. The organiser refused to say how much Tyson will be paid for his Hong Kong appearance.
