Herd immunity

As it turns out my suggestion (Reversing Course) is not novel. One of my biologist colleges noted this is what they refer to as "herd immunity".  Leaving aside the economic arguments that poverty will kill as many people as the virus (which looks rather like the trolley problem but that's for another post), the calculus should turn on how many lives might be lost under a herd immunity strategy vs. a lock-down strategy.
