Even coffee was once considered a dangerous drink. King Gustav III decided to personally test its harmfulness and conducted one of the most unusual experiments of the 18th century. The results were ironic: life turned out differently than the science of the time had predicted. This story is a reminder of how funny fate can sometimes be and how long-lasting human habits are. Coffee and tea have remained with us for centuries, and the legend of the royal experiment still evokes smiles and intrigue among history buffs.
