Finally someone that is speaking my language and isn't in a retarded tirade about mask stance extremes.
All masks are just a tool.
You don't deal with acids in with leather gloves or dip your bare hand into it.
But it also doesn't mean you submerge your entire arm in all day because you got rubber polymer gloves on.
It's not rocket science.

Indeed, the discriminating factor has always been the time spent indoors and the air exchange. It only takes a few minutes to compromise a room without air exchange. Masks at best make you earn what, a few seconds?
If people had modeled the diffusion of virions like that of odors from the beginning it would have been a thousand times better.
No need for rocket science indeed, just fart science.
#1 the type of mask
#2 Air space and enclosure.
#3 the wearer
Obviously there's a huge difference of filtration between your common paper mask an a N99. N99 greatly reduces the spread compared to traditional (but please don't wear it all day).
Gradually masks will be saturated with moisture from your mouth and nose. The average time of full saturation that compromise the mask is about 4hrs.
Obviously in a great open area dissipates the virus in the air. The smaller the area the more concentrated the spread is. So even you if you wear a mask in car ride with your bus for about 5 hrs. Guess what because of the limited space your mask isn't going to do dick once it hits full saturation.
Normally you aren't suppose to have a beard when wearing a mask. If you do, guess what. Your hair will open gaps in your mask. In construction if you are working with insulation or drywall you are required to shave before doing the job with the ppe.
So you might ask, well what's the point.
Easy to not be a dick when sick. It's for containing large water particles when coughing and sneezing to yourself rather others. That's it.
Sorry for the essay.
