Halfway through the bout, it's not looking good for Mike Tyson. He's breathing very heavily and his legs don't seem to be holding out. Remember, we have eight rounds of two minutes each scheduled in the bout. At 58, it is inconceivably tough to withstand the force of pro-level punches of a single round. Eight whole rounds is an entirely different matter. That the legend is still on his feet against Jake Paul is testament to his will and skill.
