I’ve been interested in how the human body works lately — I think basically because of our impending kiddo (birth physiology is completely amazing) and my efforts to lose some weight & get fit. I got this book because it goes through each of our systems (muscles, respiratory, circulatory, digestive, etc.) in a bit of detail — both some of the science as well as some practical tidbits about how things work better with various types of food & vitamins. Turned out to be an okay but not fantastic book — not sure I’d buy it again.
