To be fair though, Corona is incredibly tame compared to the black death. At this point, I personally am not worried if I caught Corona, as I'm fairly healthy and fairly young(only old and bitter in mind and soul). So I doubt I'd die from it(still would prefer not getting it obviously.)
I think a lot of other younger and healthy folks have that mindset. "it's unlikely to kill me, so why should I be worried about it". I can tell you though, that if this was black death deadly, or similar, I'd be pretty bloody worried
Edit-and if folks are like me, and have no children or elderly relatives or any other unhealthy vulnerable loved ones, it's even less of an issue. Both my parents are 6 feet under, and I never see my nieces. Only person I could pass it to is my brother, or roommates-who like me, would probably not die. Some folks are also just selfish, and don't care if they might pass it to a vulnerable person.
