An entirely new way of looking at the human body. Poetic, practical, and based on surprising new research. The acclaimed science writer Jennifer Ackerman lends her keen eye and lively voice to this marvelous exploration of the human body. Taking us through a typical day, from the arousal of our senses in the morning to the reverie of sleep and dreams, Ackerman reveals the body as weve never seen it: busy, cunning, and miraculous. Advances in genetics and medical imaging have allowed us to peer more deeply inside ourselves than ever before, and one of the most amazing recent discoveries is that we are deeply rhythmic creatures. The human body is like a clock -- actually an entire shop of clocks -- measuring out the seconds, minutes, days, and seasons of life. Weaving pieces of her own life with that of everyman, Ackerman shows the importance of synchronizing our actions with these biological rhythms -- and how defying them can cause us real harm. We learn the best time of day to drink a cocktail, take a nap, run a race, give a presentation, or take medication, along with a host of other fascinating facts (such as why you always succumb to a cold while your spouse doesnt even though youve both been exposed to the same sick child). At once entertaining and deeply practical, this fascinating book will make you consider your body in a whole new light.
