Nassau County in NY state passed a law this summer https://www.nyclu.org/press-release/nassau-county-mask-ban-signed-into-law YES, there are exceptions for health, religious or cultural reasons BUT they’ve also used it as probable cause to search someone https://www.nbcnewyork.com/news/local/nassau-county-police-issue-first-face-mask-ban-violation/5741363/ (it doesn’t matter that he was found with a knife. My son wears a mask because he thinks his nose is ugly)

Nature just does this. There’s no way to avoid this other than killing every living being that “travels”; plant, animal or microorganism. For example, look up the American Chestnut.
