Quite a few game boards for this game are known from the middle ages and several from Viking Age Scandinavia. 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.
As the disease gets worse, symptoms usually become more severe. Common signs and symptoms of COPD include: 1  An ongoing cough or a cough that produces a lot of mucus (often called smoker's cough) 2  Shortness of breath, especially with physical activity.  Wheezing (a whistling or squeaky sound when you breathe)
Exacerbations may be accompanied by increased amount of cough and sputum productions, and a change in appearance of sputum. An abrupt worsening in COPD symptoms may cause rupture of the airways in the lungs, which in turn may cause a spontaneous pneumothorax. In infection, there is often weakness, fever and chills.
