The face mask war is on. Some people refuse, others demand it. Personally, I think it's a good idea, even if it's not 100% protection. If it helps at all it's worth it. But not everyone feels that way and I think that has to do with what you hear. If you have friends or co-workers with stories about who they know that just tested positive, then a mask seems like a good idea. If everyone around you doesn't seem to know anyone with the virus and thinks it's all made up hoo-haw, then you're less likely to wear a mask. But if you want to fly United Airlines, you'll need to mask up.
