Too bad so many people don't even know that they are out of field when talking about masks. Doctors, economists, biologists...and even the epidemiologist chick!

Who are in field? Anyone who understands that masks wick moisture and droplets evaporate quickly in masks. You know, physicists...and maybe a few engineers.

Not the CDC. Not NIOSH. Not the AMA. They are clowns when they discuss masking.

Doofus: Well, doctors wear masks to prevent infection.

Physicist: And people carry rabbits' feet, too. If you carry a rabbit's foot when you mask, you double your protection!
