Sorry, Pudz is the world's strongest man, NOT a fighter. Getting hit in the face by someone who's trying to seriously hurt you is not the same as lifting bunch of weight. With the amount of roids Pudz has taken he'll go blank when he fights. He'll be too tensed up, too angry etc. That will tire him out instantly every single time.
He wasnt scared he was just getting too tired to defend himself and he knew it. He isnt experienced enough to control his breathing and adrenaline just yet. But what a feather in tims cap hey. great story for the grandkids... "Hey grandpa, tell us again about the time you beat up the worlds strongest man"...
There is no myth. Your testosterone levels are through the roof, it's harder for you to control anger. Not to say that anyone who uses steroids can't but it's harder. I don't need any educated fools telling me otherwise to know this for a fact.
