Many people in Japan wear white surgical masks when our in public on trains, buses, even when driving alone in a car. From the look of things, one would think that Japan is a country full of doctors. But I’m told in these crowded conditions, colds are easily passed along which is why people wear the white masks. Ironically when I visited the hospital, no one working there wore a surgical mask. Did they run out or do doctors and nurses know something we don’t?
