The link below is to the best overview of COVID19 that I’ve seen. It covers what it is, how it spreads, why soap works, how testing is done, and why social distancing matters so much. It’s from the Yale School of Medicine. Watching it may be the most important 8 minutes you’ll spend today. Thank you to Krystyna Zuberek Hincman for sharing it with her group of friends. Now I’m sharing it with mine. Oh? And Krystyna’s a real scientist.
