I've said this before -- during some past epidemics in Asia, I would see images of residents wearing masks and there would be some expert(s) saying the masks do nothing to prevent the spread of disease. Even in the beginning of this virus spread, "experts" were saying masks are useless. Then all of a sudden, the CDC, WHO and others said we need masks to prevent the spread of COVID.
So what changed?
I wear one when I go out because most places around here require masks or they won't let you in. Then today, the Goobernor just made them mandatory everywhere. I expect next will be another shutdown. I read that California's Goobernor just ordered shutdowns again for many of the state's counties. These politicians are determined to put us all back in the box. They must be stopped.
