MIKE TYSON insists he is amazed to still be alive.
Tyson, 41, saw his life gradually come crashing down around his ears after he became the youngest ever heavyweight champion at the tender age of 20 in 1986.
Iron Mike spent three years in jail for rape and managed to lose the $400million fortune he earned during his years as the world’s best boxer.
But the fallen star is finally back on the right road after ditching his playboy lifestyle.
Speaking ahead of the launch of a documentary charting his rise and fall from grace, Tyson said: “I look at it all now and I’m embarrassed.
“I don’t know who I am. That might sound stupid but I really have no idea.
“All my life I have been drinking, drugging and partying and all of a sudden it comes to a stop.
“I didn’t know how to be any other way. I felt like one of those barbarian kings just coming to conquer the Roman Empire – I was crazy.
“I never thought I would live to this age.”
