It's the comorbidities that drive the concern.
I had Rona, got it from my Dad, who was 85 and went to a gun show a week before. I had absolutely no symptoms and I'm 60. Have not been tested for antibodies, as Dad was one of the first fatalities of the fall wave we're getting in Montana (rural America).
Thing is, he wore a mask, they were temp-checking people, we kept space and nobody seemed overtly sick. But the gun show did cause a number of new cases, so SOMEBODY was hot.
Rona is nothing for most of us, but for a few, it's a stone facking KILLER.


Up hills slow,
Down hills fast
Tonnage first and
Safety last.
