I can't remember if it was here or elsewhere...but I was spitballing a week or so back that conceivably this is a part of the explanation for the major impact on Quebec and Ontario, and the fact that we've basically had no issues: remember the weather in March and early April? Everyone was outside here. I bet not so much in the east. Conceivably there were fewer D-deficient people here at the time, although I would be surprised if that were a complete explanation, of course. Still, it's funny that Quebec did way more social distancing than we did, and our outdoor space usage increased so much while theirs dropped, and we have Vancouver, and uncontrolled travel to and from Wuhan for god knows how long...and yet here, nothing happened while they're taking a beating.
I don't generally get into vitamin supplements but I started taking vitamin D a couple of months back when we were still trying to figure out how seriously this thing would hit here, just in case it was bad. Obviously not too concerned now but we didn't know it was going to be so mild, so in the early days I thought it might be worth it, just in case. I had heard from some people working on this in the US that they were seeing a possible link to D and it's so cheap, I just figured why not.
You know, there's also an entertaining German study where they found that in men, low testosterone was linked to C19 complications.
Between these two factors, ironically, there's a case to be made that the polarization in the US response actually makes some sense. Macho outdoorsmen genuinely aren't at risk compared to soy-eating indoor urbanites, i.e. there's actually an argument that this won't really hit MAGA country the way it hits Hillarytown. So why not have one party for lockdown and one for opening up? In each case they're making fairly rational, self-interested arguments.
Before somebody goes demanding links and credentials to justify this take...forget it, it's a post on a fishing forum and not intended to be a regression analysis of the spread of the disease factoring in party affiliation. But for anyone who's interested, look it up. It's been known for a pretty long time that physiology is linked to voting patterns and that bigger, stronger men (i.e. higher testosterone) break a certain way politically.
So the people who want more lockdown might need more lockdown. The people who want less, might need less.
