The best Viking Age example is the two sided game board from the Gokstad ship (c. 900). This is clearly Nine Men's Morris with its three courts. There is also what is clearly a Nine Men's Morris board on slate found at Peel, on the Isle of Man.
Jaundice is the most common symptom of bile duct cancer, but most cases of jaundice are not caused by cancer. Jaundice is more often caused by hepatitis (inflammation of the liver) or a gallstone that has traveled to the bile duct. But whenever jaundice occurs, a doctor should be seen right away.
Symptoms of low bile production may include constipation, poor digestions, gas, excess acid, headaches, and gastric or acid reflux. These may also be signs of cholestasis, a condition where the excretion of bile is inhibited. Bile excretion can be inhibited when gallstones block the duct of the gall bladder.
