Facial Hair Is Biologically Useless. So Why Do Humans Have It?

Media outlets stumbled on a 2017 infographic from the Centers for Disease Control showing which facial hair styles were OK with a standard respirator or N95 mask and which styles were less ideal because they “crossed the seal,” allowing all manner of nasty little things access to your wide-open mouth." It's worth pointing out that boxes of N95 face masks made by different manufactures that I acquired before COVID-19 struck—which I'd regularly used in industrial environments against dust and dangerous particulates—all stated that facial hair/beards would significantly reduce the effectiveness of the mask.
