This 39-minute interview with two experts is the best information available on the efficacy and dangers of masks. As I have reported from the beginning, unless the mask is N95 it provides zero protection against inhalation and exhalation of viruses: https://thehighwire.com/videos/mask-whistleblowers-tell-all/
All masks raise C02 levels, reduce oxygen levels, and, if you are infected, increase the viral load that you are breathing. If a N95 mask has an exhalation valve, the C02 and contaminant levels are lower, but if you are infected the mask does not protect others from your exhalation of the virus: https://multimedia.3m.com/mws/media/1794572O/surgical-n95-vs-standard-n95-which-to-consider.pdf
A N95 provides a tight fit unlike the masks people are wearing. Without an exhalation valve, a N95 would build up C02 and contaminant levels quicker and higher. I find it impossible to wear a N95 mask for more than one hour. According to OSHA standards, people are supposed to be individually tested before being assigned a mask as some are more damaged by masks than others.
These facts are well known by experts, so why are masks being imposed by political authorities and why has OSHA turned its back on its own scientifically based requirements?
The answer is that masks are a political agenda and have been weaponized against the people. The same for lockdowns.
Moreover, there is no basis in law for the mask and lockdown mandates. These are arbitrary illegal actions. In Michigan the state supreme court has overturned the tyrannical governor’s lockdown/mask mandates.
The American people have paid a high price for being uninformed or misinformed by presstitutes and the agendas being served by the Covid virus.
