@The Night Watchman
I share your concerns about Sweden (and the IMHE modeling). I think IMHE backpedaled using technical jargon saying that "Well, a bell-shaped curve is what our statisticians expect"
WTH? No, that's not how viruses work. Humans do things that fall on bell-shaped curves but viruses (and lightening and rock fall and all kinds of other things) do not. Viruses are going to do what they do.
I do not see how ANYONE can think that a virus would not thrive (and do all kinds of crazy curves) if we (the hosts) don't do something.
IMHE says they got the model together quickly and put in those shaded areas to show "what could happen if the bell curve doesn't work"). Well - it's clear that we, as a planet, could plateau at thousands of deaths per day, or at last close to that.
So, Sweden ended up having slightly more than half its death be people over 75. No biggie right? People gotta die. But expectations regarding lifespan and retirement - and continued expertise of well-trained people from the 20th century - are now disrupted.
Good luck training new nurses and doctors without the 60+ group teaching the higher level classes, including clinical oversight.
But, for Sweden as elsewhere, a bunch of deaths in nursing homes wasn't initially consider "a big deal," it was part of herd immunity. But, as healthcare workers began to die, they rethought that.
Also, in Sweden, it was poorer communities (nearly all of them the immigrants that Sweden controversially permitted into their nation). Poor people dying isn't such a big issue for some people. In fact, I daresay that some people's sentiments or politics run toward "old people are gonna die anyway" and "immigrants aren't that productive and they're annoying."
Better minds are prevailing in Sweden. They see the problem - they can "ride it out" or they can protect the vulnerable. Big surprise - we've seen this thousands of times in human history. Treating each person as a real, living human being - with importance - is hard to do.
Now that I'm officially "elderly," it's weird to suddenly be considered "no big deal." It's weird to see myself excluded from college meetings (if they are occurring in any meaningful sense) because...social distancing and I'm now officially in a vulnerable group. I realize that people want my job. I realize that no one really understands how long it takes to amass information on a topic (well, WSers do).
I guess it's a good thing that H. sapiens is establishing a new, lower limit for its life expectancy, even if it's just a few years. Instead of averaging 79 in the US, we'll average 76. Or 75. Or 70. Or 69. (a return to 1915?)
Doesn't really matter when you're young.
