The mask not only keeps airborne droplets in, or out. It keeps the wearer from touching mouth and nose involuntarily. This helps protect against smear infections!

I noticed this when I was wearing one during a flu infection. My fingers were frequently surprised to touch the mask instead of my face, and I went "oh, right, don't do that!"

This. Despite trying to be continuously concious about touching my face I am sometimes surprised that I absent mindedly do it. And now when I do it I am reminded and I immediately pull out my little bottle of hand gel and lather up.

It's interesting how much different, and even opposing information is floating around. Just the other day I read an article that said masks are bad because you will and need to touch your face more often...

Regardless, most reputable source for advice is probably from WHO, even though my gut feel/logic would tell me otherwise.

Most objections to masks are simply made up to justify not having to wear one. That claim is also not backed up by anything but a gut feeling, mind you :-)
