In the land of the rising sun, germs are a concern. That’s why this $15,900 “air shower” actually exists there, forcing despondent salarymen to subject themselves to a crazy wind tunnel that sucks the pollen and germs out of hiding in their various creases and crevasses before they enter an office building.
It seems kind of effective, but I prefer the American method of just wiping your snot on your sleeve. Different strokes, I guess.
