Yes. The governor of Tokyo suggested that and at least some do. I know some who do. While many of the coeds are probably wearing them for zoom lessons at home because they do not want to put make up on just for a zoom class and would rather die than be seen without make up (not a joke for many), why are some of my male med. students wearing a mask for zoom lesson when they live alone? I had a fight with one employer that demanded I wear a mask at home for their online classes.
