This is a phenomenon that commonly takes place at casino tables while gambling blackjack for a long period of consecutive time. The elbow is bent on the edge of the table either in a downward or upward position. After a few hours the hair on the arm or elbow will become smooth where the table meets the arm. There could be indentations of that part of the table on the arm. Shoulders will become stiff, perhaps even sore. Almost always the edge of the table where the elbow is laying will have short lasting non permanent indentations as well for a few minutes after the person removes his arm or elbow. Bald Arm could cause minor irritation to the skin for a few hours even after the person stops playing.
