I’m sure you’ve quit your job, right? It’s certainly not worth the risk that you may pose to someone. Has Penn State shut down? They ought to. Not worth the risk.The economy and mental health in the countries that have managed the pandemic far better than we have, is either better or far better than it is here. People in Australia and New Zealand are going out to sporting events and concerts, and they aren't burying their older relatives left and right.
On your "if you are at high risk - stay home" argument, are you saying all of the dead in the nursing homes got it while out and about? Of course not.
In any community where the prevalence remains high, it ends up finding the old, the fat, the diabetic, the immune-challenged, the just plain unlucky, etc. According to @SlickAg, our attitude should be "screw'em" but I'm not so sure everyone agrees with that.
And it's the people who aren't going to die from it, or even feel that bad from it (most of them), that keep the prevalence high. The ones who for some reason feel that depriving the rest of the community of their potentially virus-laden respiratory aerosols is somehow infringing on their freedoms. Might as well argue you should be able to go around coughing right in people's faces.
We’ve gotten to the point that if you need a vaccine, you can get one. The President said every American would have one by April 19th. If you’re unable or unwilling, isolate yourself. But April 20th marks 400 days. It’s time to get going again.
