Covid is not the only infective virus.
Our immune system is updated and reinforced regularly with contact with other people.
When masks are worn, this updating and reinforcing doesn’t occur as frequently.
Wearing a mask is sort of like not updating your computer virus program for prolonged periods.
There is a potential danger in month-after-month mask wearing. I am not sure how much, but there is a risk, which may be greater in less healthy people.
When I travel to California, I quite often get a brief cold because some of the viruses circulating in California are substantially different than those common in Florida.
The virus now is man-made. It’s Joe Biden and his political party.
