Book 29: The Body, a Guide for Occupants. A fun book about what we know about the human body based on science. It talks about the body section by section. The book is filled with trivia including a lot of mentions of people who are not well-known by folks (including some scientists whose research was co-opted by others who took all the glory). I knew some things, I learned some things, and I thought "Oh I think that's changed" about a few things (book is from 2017). Readable and fun.
