If you're wondering, my friend since 1988 and housemate since 2018, Robert D. Youngman, died on Thursday. It's going to take a while for me to get over things. He said the time he'd been with me was the best of his life, and I'll sure miss it.
He was 65, and his diabetes must've been involved in his developing such an inflammatory case of Covid-19. The weeks just prior to his catching it, his blood sugar had gone out of control by the oral drugs he'd been taking, and then even adding back Lantus (a slow insulin) injections didn't bring it anywhere near normal, and hyperglycemia's known to be a risk factor in Covid-19 deaths. He went from a little cough to dead in 3 weeks, but at least he was "out" the final 11 days, so didn't feel anything.
Seems that single shot of the Pfizer mRNA prep protected me, the only respiratory symptoms I had were from my tree allergies, and the season this year seemed even worse than last; living across the road from a tree nursery doesn't help that.
