On a more practical note, has anyone been following the mask/no-mask controversy?

The WHO told people not to wear masks - that they don't help. Presumably this was said to keep people from hoarding them away from medical personnel who obviously need them more. Others are saying even a homemade mask is better than nothing, and in a lot of asian countries, there's widespread mask-wearing. I'm thinking I may start wearing one made out of a hand towel when I go out.
