safe and effective
I need my 15th booster
BTW if one does want to wear a face diaper please be sure to shave. Proper process in utilizing masks, rule number one that was NEVER articulated to the people. Any breathing filtration that depends on a seal with the face requires no stubble, facial hair etc.... and sure wear 2 of them.....
A question (acknowledging that most people have closed down mind changing at this point):
Could it be both that (1.) masks are ineffective at a population level, and (2.) they have utility at an individual level?
