If you’d like to have nightmares, Christopher Stolarski has written up an account of his month of treatment for COVID-19. He was young and healthy, so he survived, but it sounds hellish.
I’d also say, “wear a mask,” but I guess that ship has sailed. We require them at the university and in the hospital, but outside of those places, I never see anyone else wearing them anymore. Does anyone know how to read a graph?
