Apart from the contents, which may or may not be true (I like coffee, drink it a lot, but that's hardly scientific evidence) this book is only interesting if you're a complete moron, say with a sub-zero IQ.Time after time, the same points are made. The book pretends to be scientific and has quite a list of references at the back (I still have to study it, but that's probably the only worthwhile bit about the book), but it turns out to be one big piece of sales blahblah, reminding me more of a TV shopping channel than anything close to a sound popular-science book.Again, I'm not judging the content here, just the writing style. It sucks. Probably it was written to give away with a package of Vivarin, but the company thought the better of it and thus the author went searching for a publisher....
