I definitely agree that "those who can make you believe absurdities..." What are your thoughts on the MIT studying regarding the 6ft rule (and how it doesn't actually do anything)? Given this, aren't you pushing an absurdity by pushing a narrative that has no scientific basis (again, see the MIT research)?

John Dunn

The phrase "it doesn't actually do anything" is factually incorrect.

The probability of contracting an infection is directly proportional to the organism density to which one is exposed. That density varies in inverse proportion to the distance between a person and the nearest point of organism dispersal. The six foot guideline comes from the works of highly trained experts in epidemiology, not from wanna-be, self proclaimed, variously credentialed gurus.

The three protective measures, proper wearing of a protective mask, maintaining a protective distance and obtaining a protective vaccination are required of everyone, willing or not, as life saving measures.

People get hung up on the distance and try to attribute spurious precision to the number.

d6 feet - 2 meters has the advantage that it is easily estimated - it's two arms lengths. Whether the people happen to have shorter or longer arms isn't the idea.

nor is there some imaginary barrier at 2 meters where the particle density falls to zero. It tapers off following some sort of 1/r or greater (heavy particles fall out faster), and it's well known that micron particles don't fall out at all.

You have to pick something, so pick something easy, and *good enough* - two arm lengths seems reasonable.

This is the classic problem in public health guidance - it needs to be short and simple. And it necessarily jumps over a lot of the details.

It's like food safety temperatures. Cook hamburger to 160F to ensure no E.Coli, but in fact, if you had fresh unground meat, washed, then ground in a sterilized grinder, you could probably eat it raw with no E. Coli risk. Likewise cooking pork well done to kill trichinella, notwithstanding that there are no cases of commercial pork sourced trichinosis in years.
