Considering the amount of caffeine everybody consumes all around the globe, it's amazing how little we know about this drug - and how few popular books are written about it.We know all we need to know.....from personal experience. Or so we think! Probably most of us are addicts without admitting it. And imagine the advantage you can have over everybody else if you limit your intake of this potent drug.All the cultural background is interesting. I'd be even more grateful if at least one of the authors were medically trained. But they seem to have done their homework, and I applaud their effort. Treat yourself to a nice cup of steaming hot java (preferably de-caff), and sip slowly while you savor this fun book.Another good book to go with this one: "For God, Country & Coca-Cola" by Mark Pendergrast - all you want to know about the world's favorite sugar water (caffeinated, of course!)
