In a very revealing interview on his successful career in the sport of boxing, former heavyweight champion "Iron" Mike Tyson discussed the ups and downs of being one of the most recognizable fighters in the history of boxing. Tyson, 45-years-old, became the youngest heavyweight champion of all time in 1986, when he captured his first world title at the age of 20. He later unified the entire heavyweight division.

"I was an *sshole, a spinner, a madman, an obsessed madman, a retarded psychopath, an unrestrained piece of s**t. I was a smug slimeball. I thought I was the king of the world," Tyson told Speigel. "There will never be a boxer who swallowed more pills than I did. I never thought that I would make it to 30. I'm glad that I'm still alive. Boxing made me crazy."

Tyson, who has eight children with four women, lives in Las Vegas with his third wife Lakiha, daughter Milan and son Morocco. The fight has turned his entire life around.

"I only want to be a good father. It is important to me that my children have a good opinion of me, because I have no opinion of myself. I do not drink alcohol, I don't smoke, don't take drugs. I'm a vegan - no meat, no dairy, no eggs. I eat raisins, tomato soup and drink tea. Back then I was the opposite of what I am now," Tyson said.
