Granted. Your liver does indeed process alcohol quicker, and after spending some time drinking copious amounts of every beverage you can get your hands on, you form a brilliant plan in your head.
You enter the local bar, and claim that you can drink anybody under the table, and that you're willing to bet money on it. There's no shortage of fools who wish to face the wrath of your beer gut, but you vanquish them like flies! Soon, you're a local celebrity, and after some time, gambling on for how many drinks a challenger can last has become the sport of choice in your city. You're rich and famous. No one has ever defeated you in a drinking contest.
However, what you did not consider is that your occupation creates some very attractive opportunities for instant enrichment for people of an unscrupulous sort. Once, you're approached by a man who offers you a tremendous sum for you to lose your next contest deliberately, and promises retribution if you don't do as you're told. Of course, you refuse. You have your reputation to consider.
A few days pass, and you begin to forget about the incident. But your adversary hasn't forgotten about you. When you're walking back home, slightly tipsy after another victory, you're cornered by a pair of thugs in a dark alley. They beat you to death with beer bottles, and stuff the bottles into the mouth of your corpse, mocking your carcass as it lies there broken, its eyes staring up in terror and incomprehension.
Your funeral is a closed-casket one. Your parents weep and curse themselves for not having raised you better. Your fanclub is devastated. They stand vigil at your grave day and night.
However, you are quickly forgotten. After all, all you did was drink a lot. Is that what you wished to do with your life?
I wish I had the miraculous power to resolve every interpersonal conflict in my favor.
