Dr Vitali Klitschko was known for his powerful punches and durable chin. With an 87.23% knockout percentage rate, he holds the second best knockout-to-fight ratio of any champion in heavyweight boxing history, after Rocky Marciano's 87.76% and is the 8th longest reigning heavyweight champion of all time. He has never been knocked down in any professional boxing bout. His two losses have come via a shoulder injury during a fight and a deep cut below his eye, which were recorded as RTD and TKO losses. In both fights, however, he was leading on the scorecards. His power and his possession of a doctorate have led to his nickname, Dr. Ironfist.

Education is very important.
