Masks Don’t Work:A Review of Science Relevant to COVID-19 Social Policy

Even those who tought the efficacy of wearing a mask can't agree on what kind of mask to wear, so if you really want to be protected, you should don a Level-B HAZMAT suit with SCBA in a "clean" environment, and undergo a full decontamination before reentering the "clean" environment.

Thank yo for the medical share sir.

Wow, amazing. A local newspaper, with no scientific background, publishes a "scientific" paper, without peer-review, because it supports their political view on masks.

And we're supposed to listen to that?

You've indicated that you have a PhD. You should know how this is supposed to work, even if your PhD isn't in one of the sciences.
