It's not luck! It's human durability! 

There was a soldier who had been shot, he was left behind with a gun with like six or eight bullets. They returned later to find that he had killed eight enemy soldiers, and then died. Simply because he survived longer than they could, because he was better at surviving than they were. 

It's not luck, it's not happenstance, it's not even cheating! Humans can survive just about anything save for a shot to the heart and cerebral cortex without dropping for a fair stretch of time. 

This logic fuels this circlejerk that makes human level roleplaying a joke!
