This is a great piece on social distancing and how and why to do it. Again, I am not a doctor, but it is my own personal opinion that it is too late to do disaster prep- it’s time to hunker down with what you got. If you are out of necessities, go to the grocery store in off hours and treat it like you are an extra in the Stand.
And for your idiot right wing uncles, here is a great piece in the Post on WHY you should practice social distancing. It even has pictures for the Republicans who don’t like big words.
