I don't think I've ever been above admitting when I was wrong. So, I will admit I was wrong about masks. A nice reader (whom I won't identify because I didn't ask for their permission to identify them) explained things to me and changed my opinion. I still don't agree with 'mask mandates' - but it's on a philosophical point and not a scientific one.
The COVID-19 virus is about 0.125 microns in size. An N95 mask - which most of the population DON'T have, but we'll talk about the 'best' masks we can find - can block particulates down to about 0.3 microns. That is a large window and one which the virus can easily get through.
So my science was right - at least, I still believe my science was right - as far as it goes. I, however, was wrong.
As I've been made to understand it, the issue is that the mask works to 'break the breath' of the wearer. So, although the virus can get through the mask, it isn't propelled with as much strength beyond the mask, thus - with proper social distancing - it poses a far less significant threat to the surrounding population.
So, I'm glad I still choose to wear a mask in public buildings and when I can't stay far enough a way from strangers. However, I'm happy that - at least right now - it's my choice to do so. :)
