I just finished reading The Last Dive, which chronicles the experiences and
deaths of divers Chris and Chrissy Rouse.  Interwoven into Chowdhury and
Rouse stories was the history of diving to present day and the evolution in
sports diving - deeper, longer, farther.

I had an uneasy feeling reading the book as I could see where this was
going.  The Rouse's step by step progression with every adventure emboldened
them to seek that next greater adventure.  I could see where the law of
diminishing returns played out here.  They kept pushing the limiting,
pushing the envelope on sport diving and it only took one mistake to kill
them.

I am not sure how much a non-diver would enjoy this book, but if you are a
diver, it makes for interesting reading and the backstory on our
hobby/pre-occupation/lifestyle.
