Coffee and the Fear of New Things

In the 1700s, Swedish parliament completely banned coffee. King Gustav III decided to do a health experiment that would strike fear into any wannabe coffee drinkers. He got two inmates off of Death Row who happened to be identical twins. For years, doctors supervised the experiment and reported their findings to the King. But they both lived a very long time. So long in fact that the doctors died and King Gustav III was assassinated before the experiment was completed.
