Gustav III, King of Sweden, was determined to prove that coffee is unhealthy. He conducted an experiment on two identical twins; both sentenced to life imprisonment. One twin was ordered to drink three pots of coffee every day, while the other had to drink the equivalent amount of tea. The experiment would continue until one of the twins died.
Gustav III did not live long enough to obtain the results of his experiment; He was assassinated in 1792 while it was still in progress. The two physicians who were appointed to supervise his research also both died before the completion of the experiment. Eventually, one twin died at the ripe old age of 83 years. The first twin to die happened to be the tea drinker.
