A recent image of Tyson standing with his shirt off is proof that the 53-year-old is fighting fit.
Earlier this month, the former heavyweight champion posted training footage as he announced his intentions to take part in three or four round exhibition fights.
And all his recent activity points to a return to the ring in the not so distant future.
Tyson has been on quite a journey in recent years. He once stated that he was a cocaine addict and it was in 2009 when he realised he had hit 'rock bottom'.
Four years later, in an interview with Oprah Winfrey, 'the baddest man on the planet' spoke about his transformation, including the decision to become a vegan.
"Well my life is different today because I have stability in my life. I'm not on drugs. I'm not out on the streets or in clubs and everything in my life that I do now is structured around the development of my life and my family." he said.
"I lost weight. I dropped over 100lbs and I just felt like changing my life, doing something different and I became a vegan.
"Becoming a vegan gave me another opportunity to live a healthy life. I was so congested from all the drugs and bad cocaine, I could hardly breathe. High blood pressure, almost dying, arthritis and once I became a vegan all that stuff diminished."
It's remarkable to think that the former world champion once stated that he started to fight prostitutes while high on drugs, as he was paranoid they wanted to steal from him.
He explained to Las Vegas Weekly in 2012 per Daily Mail: "Laying in bed in a hotel room - I try never to be alone, even if it's a prostitute, a dog.
"This is really dark. I am in my hotel suite, I've got seven women there, and I have a morphine drip, and I had my cocaine, and I had my (Viagra-like pill) Cialis, I had my marijuana, I had the Hennessy.
"And I am at my lowest point because I got paranoid and I thought these women were trying to rob me and set me up.
"I started beating them. I was in a dark place. There was a purpose, though, because I didn't want to give them any more of my soul.
"So this is my devil, this is where I am, I am locked up alone. There is nobody there telling me that I'm doing too much.
"That is the devil, he won. I kicked them all out. So that was my lowest point. Oh, man. I am just very grateful to be here - my heart should have blown apart."
