Version 3
Masks are being widely recommended as protection against the COVID-19 virus, both to protect the wearer from infection, and to protect others from wearers who do not know that they are infected. Trouble is, most of the scientific evidence and recommendations are against the use of masks by the general public. Despite this they are increasingly mandated. In some places you cannot walk around outside without a mask, in others you cannot go inside a public space without a mask. Workers are often mandated to wear them. And now airline passengers, no matter the length of their flight.
