It is getting difficult to go out into the world without a mask, even though I have never believed they are effective. When I try to discuss it with someone, they say, "You can find an argument for either side." I'm looking for truth--not other opinions. This man seems to have done his research so thought I would post the link in case, you, like me, would like the truth and to be able to support it. As I have always believed, the evidence supports that masks are ineffective because the virus is so small.
