I did enjoy reading this book and I did learn a couple of those classic titbits to inform, or annoy, friends with. I now know why we get The Bends; what temperature your brain cells die at; that Mt. Everest is coincidentally at the absolute limit of what humans can survive without breathing apparatus; and some historical details on early diving bells and the Mariana Trench. That said, this book is incredibly `hard going'. This isn't necessarily as a result of the scientific content, which although sometimes difficult to grasp at the first pass, isn't truly that difficult. It comes as a result of the author's laboured style and overly convoluted pros. I did feel like I was expected to have a prior knowledge and understanding of the subject. Like I said I wasn't looking for a `beginners guide' and this book wasn't technically demanding, but the explanations are so befuddled that it was impossible sometimes to follow the thought pattern (there were very few diagrams, graphs, and/or charts, that in some instances may have gone a long way to succinctly explaining the issue).
I don't think this book warrants a `1' or `2' star but it's certainly not one of the best popular science books I've read in recent times. It had the potential to be a superb book, with an engaging and interesting subject matter. However, it falls short of this and manages to make some parts very dull. I did read the book cover to cover, unlike the people that review what they've "given up" on, but I have to confess it took me a lot longer than usual. Maybe this is something for a coffee table or chapter-by-chapter `dip' over the course of a few months. If nothing else it may simply inspire you to further reading on the very interesting topics.
Just as an aside. I take exceptional care of my books but found that by the end a couple of pages were falling out where they had become unstuck from the broken spine. Wasn't happy!
