Very good question. My thought is that you would have to set up very specific "practice parameters" and that an overwhelming percentage of the population would have to follow to a "T".

I honestly think we're in a "culling"; vaxxed or unvaxxed. A modern day "bottleneck" if you will. There are other factors, but I get the sense, that that's what we'll find in the end. It's a matter of degree imo.

This has been the history of our species; why would it change now? Especially now; since we are so "mobile" and interconnected.

Perhaps there's nothing we can do? IMO the hubris of man has made this situation so much worse.

I'm concentrating on the basics of health. At the end of the day, that's the one thing I can control. And the one factor that determines overall fitness during "events" like now.

It's no guarantee; but I like my odds better that way than looking for a magic bullet. Perhaps there is a magic bullet? I don't know; but I have a feeling it will be too late.

EDIT: "vaxxed with 2 shots or less"
