Each chapter in this brief compendium was prompted by something related to the COVID-19 pandemic which, in turn, led me to recall a subject often far removed from where I began. While digressing, I rejuvenated several oldies from my previous twelve books about medical history and added a few newbies. The titles of the last four of my books all included the word meanderings, but this time I’ve chosen to describe these essays as ramblings. I really don’t know why the change. Perhaps COVID effects the brain. In fact, I’m sure it does and this rather disjointed collection is the evidence.
