Harrison is one of the most intriguing presidents when it comes to health. At the time (in 1841), Harrison (68) was the oldest US President. (The record holder for oldest US president is #45, but the oldest legitimate US president was Ronald Reagan). Harrison gave the longest inaugural speech in US History (1 hour 45min) on an extremely cold winter day. Many say that Harrison did not want to appear old and weak, and therefore gave his speech without a coat and gloves. The next day, he began feeling ill and soon the illness turned into pneumonia and eventually Harrison died just 31 days into his presidency.
