I think drinking a quart of Jack Danials every day would stop Covid in its tracks. The trick here is few would ever be sober enough to leave home so they would be avoiding everyone else.
Hal Holbrook's "Mark Twain Tonight" featured this story (abbreviated and paraphrased):
"I was taken ill once, and sought the advice of a doctor. He told me to drink a quart of whisky a day until the illness passed. I thought that was good advice, but nevertheless felt it prudent to seek a second opinion. Well, that doctor prescribed the same thing. That made half a gallon. I'd been drunk before, but that was a masterpiece!"
