Former boxing heavyweight champion Mike Tyson has revealed how womanising may have been one of the biggest reasons for his downfall as a fighter.

According to a report in British tabloid, The Sun, Mike, 53, retired from boxing in 2005, but filed for bankruptcy two years earlier even after having earnings over $300 million (approx R2,272 crore) during his career. In his autobiography, he spoke about having sex with different women on a regular basis even when he was in jail for a rape conviction. Mike said: "I was having so much sex that I was too tired to even go to the gym and work out. I'd just stay in my cell all day."
