The sight of the most brutal knockouts in boxing history can be so gory that one may begin to wonder if such boxers have any humanity left in them.
Sometimes, it looks like they are a pure breed from a beast covered in the flesh and wearing a glove.
The adrenalin-pumping moment can be entertaining and scary to spectators at the same time.
Most times, what is regarded as a knockout is a lifeless body dropping down and convulsing as they will never make it back on their feet.
Indeed, boxing is not for the fainthearted.
