Book excerpt: This “seriously entertaining book” explores the skin in its multifaceted physical, psychological, and social aspects (Times, UK). Providing a cover for our delicate bodies, the skin is our largest and fastest-growing organ. We see it, touch it, and live in it every day. It is a habitat for a mesmerizingly complex world of micro-organisms and physical functions that are vital to our health and survival. One of the first things people see about us, skin is also crucial to our sense of identity. And yet much about it is largely unknown to us. With rigorous research and lucid prose, Monty Lyman explores our outer surface through the lenses of science, sociology, and history. He covers topics as diverse as the mechanics and magic of touch (how much goes on in the simple act of taking keys out of a pocket and unlocking a door is astounding), the close connection between the skin and the gut, what happens instantly when one gets a paper cut, and how a midnight snack can lead to sunburn. The Remarkable Life of the Skin takes readers on a journey across our most underrated and unexplored organ. It reveals how our skin is far stranger, more wondrous, and more complex than we have ever imagined.
