Someone is making a LOT of money off these masks, and all of the blue ones I have seen are made in...
*Yeah, you guessed it. CHINA.
But to change gears, the human body responds to long term low grade hypoxia by making more red blood cells over time. Athletes discovered this, and by training at high altitudes, their bodies built additional red blood cells to carry oxygen to their organs and tissues to make up for the atmospheric deficit in oxygen at altitude.
There was even a kerfuffle in world class sports over "blood packing" a few years back.
After working a month at 9,000 feet, I, too, noticed that at the mere 2300 ft. elevation of home, I had substantially improved endurance while doing physical tasks.
Which leads me to wonder if there is any link between masking, "blood packing", and the thromboembolic events that seem to accompany getting the jabs, or even just getting COVID itself.
