I had an old friend who had a wooden leg. His leg was attacked by stinging bees. The result was that the wood swelled up to over three times its original diameter and rent his trouser-leg assunder! I told him he should have been wearing shorts. Anyway, as he tried to walk home, the swollen wood became so weak, that his leg broke. My friend was remarkably agile, and wasn't hurt by the fall. He did get up and hop to the nearest wooden leg factory, some 2,500 km distant. They fixed him up the next day. Please note that this series of events did not take place in Australia.
