The 68-year-long case of the hiccups

In 1922, the 29 year old Iowa-born Charles Osborne was attempting to slaughter a 350 pound hog when it fell on him, which, for some unknown reason, caused his hiccups to start. They ended in 1990. Osborne died on May 1, 1991, due to complications from ulcers, and hiccup-free.
