We've never had it before. Nobody alive remembers a worldwide pandemic and the phases it went through, the unstoppable procession, the variations, the randomness of how some people get it as a mild form, while others get it and go super critical, while riding it out, then not even realizing they needed to be in an ambulance until they drop dead on the lawn and people think you should be able to do something about it, but you can't even make them live long enough for the ambulance to arrive.
I have had many different views. You look back and think, OK he had one of the famous co-morbidities, but you never knew it. Hell, he must not have known. You hear of somebody dying and then hear "well, he was x, y, z, though seemed normal to you, just days earlier. Do most people know if they have one or more of the famous co-morbidities? After 2 years, I am pretty tired of hearing the phrase.
I am not too sure about the foretold herd immunity, more or less believing in the new paradigm.
What are people doing with it? The best they can, collectively and individually according to their own perceptions. I don't call the shots and neither do you. I have had it, beat it, and not particularly a special physical specimen. I have and will take precautions when they may do some good, but generally just going about my life. For me and mine in my situation, it's the way to go. It is for communities and individuals to go forward their way. I will not agonize over the decisions of others, accept the ones that knew what was going down but, made it worse for their own benefit. I put trump in that category. At times Fauci, other times not. I guess it's the difference between foolish and malicious and individual perception.
