Interesting new information: Somebody asked Dr. Fauci how much Vitamin D3 he is taking every day. He replied "6000 iu per day", which is actually higher than I have been recommending. The USRDA is 600 iu per day, but is just enough to prevent rickets, which ignores the last 20 years of research that shows Vitamin D interacts with every immune system cell.

New paper in the New England Journal of Medicine that suggests universal mask wearing as a form of variolation. This comes from the centuries-old practice of inoculating people with just a bit of smallpox pus, so they get a mild or asymptomatic case and immunity. Not something anybody would do on purpose with SARS-COV2, but since you have to go food shopping, or to an essential job, you might as well give it a try by wearing a mask all the time when out.
