The mask is to protect others from you, not you from them. I do agree though, if everyone wore masks when we are anywhere near other people it would go long way to slowing this down. So we wear masks for that reason, because it is the responsible thing to do, even according to the CDC now. This is because they have found out that the virus hangs in the air much longer than they thought, so it isn’t just through droplets or surfaces that you can get infected, and the six foot thing may actually not be enough UNLESS we are all wearing masks too.
