I wonder if we shouldn't adopt the Japanese custom of wearing a mask when sick. I know you would look silly, but if a mask could stop the spread of airborne contagions. I also think it would cut down on the risk of acquiring a contagion through touch, because a person is far less likely to wipe their nose or cough directly into their hands if a mask is worn.

Just an idea, and not one I would die on a hill for defending it.
