To paraphrase a saying, you can't fix stubborn. Especially now, with respect to COVID-19. So much misinformation, such simple rules, so many people misquoting and/or misbehaving.
I'm in good health, but over 70. That places me in a higher risk group so I've chosen to self-isolate as much as I can. In the last 4 weeks I've managed to limit my shopping to 4 times - twice for groceries, twice for the drug store. It helps that I was always an introvert, and comfortable with myself, so for me being alone does not mean being lonely. A credit card and willingness to use Amazon also helps.
