When someone else coughs or sneezes around you while out and about ignoring the virus, you will wish that person had a mask on.
The mask prevents droplets from flying through the air, Then everyone can debate how far those drops can spread.
One can not go into a Drs office or Hospital without a mask on.
But clearly all the Drs and Nurses are ignorant on these matters.
Just go with the Herd Immunity theory, some have to die so others can build up immunity. Follow the lead of that Christie guy.
