There was a thread on another site back when the lockdowns began in Italy that surmised IF we could adequately prepare from a governmental and societal standpoint, a 40 day lockdown *everywhere* could eliminate most airborne respiratory diseases and possibly many other diseases besides. And the *trillions* of dollars that would be saved from time off work, hospitalizations, vaccinations, etc over the subsequent decades.

It would be like life without smallpox. We don’t even think about smallpox anymore except in passing mention...our ancestors feared smallpox and couldn’t conceive of a life without that fear.
