It’s not just that. They distrust science and medicine in all things. These are fat, gullible people, in overall poor mental and physical health; exceptions have only skated by on dumb luck. If they didn’t believe the docs on virus prevention, they don’t believe them on obesity and lung disease prevention either. If they didn’t wear masks for COVID, they don’t wear them for spraying paint remover at their jobs.
It’s industrial hygiene and physical and mental hygiene to which they are ignorant, personal hygiene, too. If they didn’t social distance to stop the spread, they dont wash their hands after taking a huge messy shit.
