Mary Roach does it again. Her writing explores things we wonder about.
In “Grunt: The Curious Science of Humans at War,” Roach scrutinizes the experience of combat from the viewpoint of a curious scientist; including the effect of sand, grime, sweat and other bodily fluids on the combatants. Did you know that real fashion designers work to create the camouflage uniforms we see? How about the important role played by color and texture in keeping soldiers safe? Scientists test body temperatures to see how well their bodies cool themselves, and Roach goes into detail about the process. Roach even goes undercover to experience first-hand the situations behind the protocols.
