"The primary way of person-to-person corona virus transmission is via aerosols or small droplets created by breathing, sneezing or coughing. The reach of exhaled air can be effectively reduced using a face mask as shown in our video. A simple Schlieren imaging technique is applied to visualize the air flow caused by a person breathing and coughing. Using a face mask the exhaled air flow is blocked reducing effectively the risk of infection. Also nicely shown is the heat transfer from the body to the cooler ambient air. More information about the Schlieren imaging technique is given here. "

So, when should we expect mandatory testing for COVID-19 and the wearing of masks in public?
I guess you’ll be wearing a mask from now on. That’s ok - it makes it easier for the rest of us to identify you.
Also, I see you’ve put this same graphic on multiple threads. You’re just a spammer.
Breathing? You but that? Stay 6 feet apart and screw the mask. It’s un-American.
In other words, using a face mask restricts proper and healthy breathing.
The mask isn't enough; they need a full face shield and gloves while they're at it.
They also need to fully endorse removing illegal aliens and building the wall.
...or they can embrace virtue signaling hypocrisy.
