I love beer! Usually, don't drink 15 cans in a siting, but not going to judge.
Doctors in Vietnam saved a 48 year old man's life by pumping him full of beer. Apparently the guy had been drinking alcohol, but not the kind we all normally drink. He was drinking methanol, which is used to make things like formaldehyde, antifreeze, paint thinner, and gasoline. Beer is a different type of alcohol- it's ethanol.
Doctors knew that if they fed this guy beer, it would keep his liver busy enough processing the ethanol to keep it from fully processing the methanol, which would have killed the guy. So they loaded him up with 15 cans of beer, which gave them enough time to get the methanol out of his system and save his life.
