What insights does The Black Death: A Personal History provide into the experiences of the average person in the Middle Ages?

I suppose we can consider our own experiences with Covid-19 and then multiply the misery by about ten thousand. Most people who acquired the plague didn't just get sick, they died.

People were terrified, paranoid, and ill-equipped to handle even a mild illness let alone the deadly plague.
