As always there is a problem with this so called study. Not real world situation at all, comparing apples to oranges. It really proves nothing based off of multiple studies I have read on masks that once you wear it for any amount of time the mask deteriorates, people coughing/breathing, etc would change the outcome also of this so called study
This study is not real world situation so it really is useless in trying to compare humans wearing it in an everyday situation
Masks become contaminated quickly, the masks do not block the virus going in or out when we breathe as it is small and goes through the mask
especially more so when the mask has become saturated with our breathing, The virus goes around the sides of the mask also...etc, etc, etc, etc
Next to the word ignorant in the dictionary they must have your picture...
When I read what you post I think I lose I.Q. points
