There's a lot of cool stuff about the Black Death that epidemiologists and historians dig into to figure stuff out. Before the plague, the age of marriage had gotten quite late, like 25-26 is the number in my head from history but, when 1/3 of the population was wiped out, all of a sudden there was more $$$ to go around so people got married in their teens again. Perhaps we'll toss in some useful bits, given how awash in data we are!
Yea. Signature required is the way to go, if you can. When I was working, I had my CGM sensors sent to work. as I get my insulin from a pharmacy. Sensors are very heat sensitive, so sitting in the sun was not and option. Teeny town--maybe some delivery options? friend, store, bank--somewhere people know you? Connections are important.
