With Hillary Clinton falling victim to pneumonia, in a move to show how human and relatable she is to voters, people in the media have been highlighting the many other ailments that Presidents have suffered. And whenever we talk about Presidential ailments, William Henry Harrison (who died in 30 days) is always one of the first people to be discussed.

Traditional wisdom holds that Harrison gave a long speech on inauguration day, refused to wear a hat on a cold day, contracted pneumonia and died only a month into his term. A cautionary tale used by every mother who wants her kid to wear a hat outside. And hey, even Harrison's physician said he died of "pneumonia of the lower lobe of the right lung, complicated by congestion of the liver."
