When I see a person wearing a Mask in Public I think,
Wearing that mask, is that a Fashion statement or are you just declaring your stupidity to the rest of us?
The guidance given to wear any type of covering to protect others and a good mask to protect yourself. came almost word for word from my cardiologist and gastroenterologist two weeks apart.
Neither of which is a virologist. Nor does it seem do they have any common sense.
The covid 19 virus cell measures somewhere around 20-30 nM, maybe even smaller in diameter.
An n95 mask is made to filter out 95% of particles measuring about a micron or so in diameter. Other bandannas etc. are even more worthless.
The difference between a micron (a millionth of a meter) and a nanometer is 1000 or an order of magnitude smaller. Example particles of smoke are measured in microns. You can't even see a virus cell with an optical microscope, it takes an electron microscope to get the job done. 20-30 nM is the wavelength of ultraviolet light for pity sake.
You may as well fashion a mask from chicken wire for all the good it will do.
Tell that to your doctor dodos and anyone else pumping mask smoke up your ass. Perhaps they forgot or worse yet they never knew how small virus cells actully are.
