re: ALL hospital staff HAVE to wear masks ALL DAY. Making my wife sick

My professional life as an "Industrial Hygienist" gives me some insight here and I am telling you, in my professional opinion, this is more than your usual "griping staff". Bodily fluids from just breathing, accumulate on the inside of the mask, making it less porous. That in turn keeps more CO2 present for re-breathing and that ain't good. It also becomes a breeding ground for other "gradoule'. There ARE ways to mitigate this, administratively BUT, trust me, not a good idea, day after day.

Lack of proper oxygen/co2 exchange can be a gradual killer the same way slight obesity, slightly high BP, other "slight" conditions.

Those conditions will not kill you today but keep it up every day and that adds a ton of stress to the entire human body. Like the high BP may take years but one day in the future, BAM! stroke or heart attack. Now add a 2nd stressor to the high BP like improper oxygen/co2 exchange.

C'mon roll those die, no snake eyes!
