" that's mother nature's survival of the fittest."
Not sure that excludes survival of the "smartest", in that very few at top of success in any area, are dumb.
Also meaning staying away from others that MIGHT have COVID, has never meant "staying at home in seclusion and letting one's health decline", that is a choice, and IMO not the smartest or only way to protect oneself.
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
