Alcoholism Will Kill You

 Even when you are Alexander the Great (just finished reading a book about him):

The conclusion Gerasimidis has reached after decades of research is that Alexander the Great died of acute pancreatic necrosis. This condition is believed to have been caused by cholelithiasis, or gallstones, in combination with a heavy meal and a large quantity of wine.

I was kinda taught he died of typhoid fever, but now they are saying otherwise. Keep in mind that this guy survived pneumothorax caused by a spear (or maybe an arrow, I forget which) through his lung a couple of years before, without modern medicine. He also survived many other injuries, acute pneumonia, years of heavy fighting etc only to die at 32 from too much alcohol and fat in his diet.

Many of these "died suddenly" cases conspiracy theorists love to talk about are explained very simply by drugs or alcohol or the combination of the two.
