Former heavyweight world champion boxer Mike Tyson has described his life as a "joke" after writing his memoirs.
The 47-year-old has opened up about his tumultuous life in autobiography Undisputed Truth, where he has claimed to have struggled with drugs, alcohol and sex addiction.
"Working on this book makes me think that my whole life has been a joke," the Daily Star quotes Tyson as saying.
The former boxer served three years of a six-year jail term after he was convicted of raping 18-year-old Desiree Washington in 1992.
