It is weird to me to see people treating the 6ft like a hard barrier rather than a probabilistic guideline.
If you look you'll see this behavior across a wide range of issues.
It's always hard to explain, and then after explaining the probability stuff ... you get to explain that it is the probability ... that we know of.
For anyone who wants hard facts on COVID-19... science will tell us in 2 or 3 years I suspect.
