	The coronavirus diameter is .06-.14 micrometer. It is a fairly large virus ( [https://www.sciencedirect.com/science/article/abs/pii/S0021850220300987 Ou. et al. 2020]). A big question is why, from a physics point of view, a mask should be more effective against exhaled particles than inhaled ones. After all, the air a person breathes out has to get into the room somehow eventually.		The coronavirus diameter is .06-.14 micrometer.

 *[https://www.medpagetoday.com/infectiousdisease/infectioncontrol/16278 2009 Medpage Today] article on use of masks against disease and during surgery, A very balanced article that discusses conflicting studies.
 *[https://www.wired.com/story/how-masks-went-from-dont-wear-to-must-have/ Wired magazine] had a  good pro-mask article that  lays out the flip-flop in recommendations and tries to justify them. Note that [https://www.sciencedirect.com/science/article/abs/pii/S0021850220300987 Ou. et al. 2020] does not in fact really say masks work, because they tested for up to .4 diameter particles and that article's main purpose is to look at how to clean masks.
 *[https://cnsnews.com/commentary/dr-jim-meehan/surgeon-destroys-myth-if-masks-dont-work-why-do-surgeons-wear-them Dr. Meehan]  strongly says that masks are useless against viruses and describes how surgeons wear  special masks in high-oxygen conditions to prevent droplets even though studies hve shown masks reduce the surgeon's performance.

	*New reason to carry a mask. Mr. P. asked if anyone had some string to tie off the intestines of a sheep we were butchering. Voila! Perfect length and elasticity. Carrying masks, you always have string at hand. Might replace the paper napkin for graphs, too.		*New reason to carry a mask.
