Masks deprive our brains of oxygen and leads to illness now and later on in life.

!! Must watch!! Check out this test - as this gas/oxygen meter alarms, usually you would need to move to get out of the depleted environment to get to somewhere safe with a higher oxygen level, however this is the environment 'worksafe' wants to allow us to work for hours on end and many all day long. It is absolutely dangerous and disgusting, not only does it down regulate your immune system to become sick short-term but also starving the brain of nessersary oxygen leading to dementia and more later on in life. Just following orders isn't going to cut it when all this is said and done.
Warn them now!!
