When tea and coffee was first introduced to Europe in 18th century,people thought they were harmful. So the king of Sweden decided to find whether this was true or not. It was happened that there were two brothers whose were in prison at the time. The king ordered one of them to drink tea every day and the others coffee. Both of them have lived many years without any problem. At last the one who had to drink tea every day dead at the age of 83 and the other lived even long. Because of this,Sweden is today one of the countries where many tea and coffee are drunk.
