Now I don't want to quibble about any current vs. August data, but when factoring in Aragoto's personal experience, you'd have agree that folks under 70 are not "Free to move about the cabin".
Aside from the direct risk of COVID death and long term negative effects, my ID and ICU doc friends texts sound very loud alarms...they are hearing from their peers in middle America (e.g. Nebraska, South Dakota) of hospitals being overrun, with the effect of MI's (heart attacks) and Bowl Obstructions, to name just a few, not getting the immediate care they demand. Any talk of "Herd Immunity" or just letting the pandemic 'run its course' is inviting a HC catastrophe...just saying.
