In this entertaining book, biopsychologist Mark Blumberg explores the many ways that temperature rules the lives of all animals (including us). He tells wonderful stories of evolutionary and scientific ingenuity - how penguins withstand Antarctic winters by huddling together by the thousands, why people survive hour-long drowning accidents in winter but not in summer, how certain plants generate heat (the skunk cabbage enough to melt snow around it). We also hear of systems gone awry - how desert species given too much water can drink themselves into bloated immobility, why anorexics often complain of feeling cold, and why you can't sleep if the room is too hot or too cold. After reading this book, you'll never look at a thermostat in quite the same way again.
