That brings us to a story oft-referenced, but rarely cited. According to legend, Adolph’s son King Gustav III sought to make his father’s flip-flopping coffee bans stick by devising a sick experiment. He stayed the execution of two men sentenced to death, the story goes, under the condition that one drink copious amounts of coffee daily and the other stick to the same quantity of tea. Some versions of the tale say this “clinical trial” involved identical twins, which would be quite the advanced choice, scientifically (and would represent one extremely delinquent family), so I think it’s safe to say that detail at least is fabricated. Everyone sharing the story seems to agree that Gustav’s plan backfired, with the study subjects both living into their 80′s (long after the king himself perished) and the tea-drinker dying first.
