An 80-year-old Norwegian man named Bernt Aune "had a cornea transplanted into his right eye in 1958, from a man born in June 1885. At the time it was expected to work for only 5 years," reports a New Scientist blog, which also wonders if the antique eye might only see in black and white. The cornea is still kicking 50 years later, making it the oldest functioning organ around.
