Why is it that the self-proclaimed smart people are surprised by people in general acting rationally?
We have the demographics on lethality, and if you're under 30, your chances of dying from COVID-19 are about the same as your chances of dying from the seasonal flu. Those of us in age ranges where the case fatality rate is upward of 3% are going to be cautious, while the young, quite rationally, will go back to their lives as usual given the chance, are doing so, and thus catching the disease, getting sick for a couple of weeks, then going back to their lives as usual after they recover, the same as they would for the flu.
