Sex Sleep Eat Drink Dream takes an insightful tour through a day in the life of our bodies. Divided into morning, midday, afternoon, evening, and night, Ackerman explores how we are very much driven by internal clocks that guide our daily rhythms. She does a great job of intertwining biology with plenty of interesting anecdotes. This is not a medical book but rather an informative commentary on the wonderment of the human body. Being one who loves factoids, I found some great ones in this book including:

• Air released from your lungs when sneezing travels at 500 mph.
• Coffee’s flavor is 75% smell. In fact all flavors are mostly smell.
• Thinking about exercise can actually boost strength in the muscles involved. This is the best excuse to avoiding exercise that I’ve heard!
• Yawning is contagious in only about half the population, and it’s probably the half with the most self-awareness and empathy.
• The amount of calories we consume in foods may not be a fixed value but rather influenced by the nature of our gut microbes. That doughnut may have 30% more calories for you than your neighbor.
