The biggest champions of heavyweight boxing have all been subject to extraordinary comebacks. Maybe it will soon be 29-year-old Mike Tyson´s turn to launch a new challenge: to become world champion once again after more than three years in an American penitentiary.

It might just be good to know a little more about Mike Tyson´s life and his career.
