74, that’s a great way of putting it. The extent to which you can see your breath in cold weather is where an infected person would be potentially spreading the virus. Pretty much anyone in close physical proximity to you, especially if they are breathing hard. CDC’s non-airborne argument is a technical one which they don’t explain to the public. In their world airborne is going to be just floating around in the air like spores. I wonder what the viral load is in exhaled breaths relative to other bodily fluids.

What comes to mind are the cultural norms for personal space. Americans tend to want more space than certain other cultures. I had a Puerto Rican friend at work and was forever backing away from her because her norm was only about half what most Americans find comfortable. Those cultures that go for very little personal space will be at greater risk.
