The faces of sheep.
Masking cannot possibly be healthy for people in any way. A surgeon or a nurse putting on a mask for short periods to preven BACTERIAL contamination is a different thing from people sealing themselves up all day and everywhere. They are breathing and rebreathing the same low-oxygen air, letting the staph bacteria that is normally present on skin thrive in the warm, humid environment under the mask and enter even the pores on the skin..not to mention some existing blemish...causing a staph infection, and having the infected air forced up over the mask and into the eyes. There has never been a situation in which any sane medical professional has encouraged the wearing of masks all or even most of ones waking hours.
People who develop health problems from this need to start suing.
