I recently tried to determine blood pressure recommendations for seniors because my 82 year old father in law got tired of fainting and quit taking his blood pressure meds. I was amazed at how little consensus there it concerning blood pressure readings for seniors.
I heard of a thing called covid and tried to find a consensus about mask/no mask; cloth mask/paper mask; vaccination/no vaccination; boosters/no boosters.
I was amazed at how different physicians felt so differently about the entire subject.
I don't have much faith in "physicians" who "theorize" about "naps and dementia", as they don't have a very good track record about anything else.
20. Masks don’t work. At least a dozen scientific studies have shown that masks do nothing to stop the spread of respiratory viruses.
One meta-analysis published by the CDC in May 2020 found “no significant reduction in influenza transmission with the use of face masks”.
Another study with over 8000 subjects found masks “did not seem to be effective against laboratory-confirmed viral respiratory infections nor against clinical respiratory infection.”
There are literally too many to quote them all, but you can read them: [1][2][3][4][5][6][7][8][9][10] Or read a summary by SPR here.
While some studies have been done claiming to show mask do work for Covid, they are all seriously flawed. One relied on self-reported surveys as data. Another was so badly designed a panel of experts demand it be withdrawn. A third was withdrawn after its predictions proved entirely incorrect.
The WHO commissioned their own meta-analysis in the Lancet, but that study looked only at N95 masks and only in hospitals. [For full run down on the bad data in this study click here.]
Aside from scientific evidence, there’s plenty of real-world evidence that masks do nothing to halt the spread of disease.
For example, North Dakota and South Dakota had near-identical case figures, despite one having a mask-mandate and the other not:
