The CDC states "at least six feet", which to me suggests that six feet is the minimum and more is better, particularly if the person next to you is coughing or sneezing. Is all common sense out the window? Are people really that dense? Or is it that they can't read words on a page? Or perhaps psychological problems are involved? Do they find experts disagreeing under every rock? Perhaps some traumatic event? When they take their car in for routine service and the mechanic suggests changing the oil, do they get a second opinion? What about brake pads? What if the waiter recommends the catch of the day?
