What do they call that?Wrong.
Traffic laws ate the single most important means of preventing vehicle accident.
Oh' yeah.....................precautions.
Why?The problem with masks is that they prevent an epidemic from ending, so make it go on forever, killing the maximum number of people
You only want to go with masks for the vulnerable,
They're useless.....................right?
or if you are using a full quarantine strategy because the epidemic is too lethal, like we did for Ebola.
