() I might owe my fast reading of this book to my Starbucks coffee run, but it could also be attributed to the good and interesting writing in this book. “Buzz: The Science and Lore of Alcohol and Caffeine” by Stephen Braun is a captivating discourse on two of the most beloved substances on the planet. At one moment you are a molecule-sized scuba diver following the path of the ethanol molecule throughout the body and the next you are sizing up the athletic advantages of caffeine. The first half of the book is dedicated mainly to alcohol and its effects on the body and brain. The second half discusses caffeine. While the book may be a bit outdated (published in 1996), it still has relavent information for lay readers interested in how caffeine and alcohol work in the human body. The book really left me wanting to know more of the unanswered questions about how these substances work on a microscopic/molecular level. I felt that the first half covering alcohol was more complete, and ultimately more interesting, than the caffeine part, which is why I give this book 4 stars instead of 5. A good read nonetheless and you will come away probably knowing more than you do now about alcohol and caffeine.
