If you have ever wondered EXACTLY why and how humans get altitude sickness, what happens to the body when exposed to extreme heat or cold, why scuba divers sometime get the "bends," or what would happen to an astronaut if the Space Station developed a leak, this book is for you. Frances M. Ashcroft explains in complete detail - the detail that is so often lacking in the popular, dumbed-down modern media - why the body at high altitudes can't get the oxygen it needs, what happens to skin cells when you burn yourself or get frostbite, how nitrogen dissolves in your blood when diving deep in water, or how your blood would boil if exposed to the emptiness of space.
And she doesn't stop with humans. She examines the extremes of the animal world for creatures able to withstand and thrive in boiling cauldrons, the extreme depths of the oceans, or the extreme cold of Antarctica.
She presents not just a world of creatures living in incredible environments, but precise descriptions of how this is all accomplished. This makes for Really Amazing reading!
