YOU: The Owner's Manual: An Insider's Guide to the Body that Will Make You Healthier and Younger

If there ever was a pair of docs who can make the small intestine seem truly intriguing, here they are. Dr. Mehmet Oz is an alternative-medicine maverick and a cardiologist known to implement acupuncture during open-heart surgery. Dr. Michael Roizen developed the RealAge concept of calculating one's biological, as opposed to chronological, age. Here they've whipped up a witty guide to the workings of the entire body, appropriate not just for those who can't tell their pancreas from their pituitary. Even Cheers' Cliff Claven types who think they know it all will likely be humbled by the 50-question "body-quotient" quiz that starts off the book.

With much sassy humor (they describe the adrenals as similar in shape to Mr. Potato Head's hat), they give a guided tour of the body's anatomy and major systems (hormonal, nervous, digestive, sensory, etc.) including plenty of fascinating trivia along the way. How often should you get your thyroid level checked? How much gas does the average person produce in a day? And, most important, how many times a year do most people have sex?? Drs. Oz and Roizen know. They also reveal plenty of bizarre (and potentially life-saving) facts such as this: If your earlobe has a prominent vertical wrinkle, it's likely that your arteries are aging faster than they ought to be. If only 8th-grade health class had been this fun.

The docs' main goal in presenting all this info is twofold: first, it's your body, so shouldn't you finally learn how it works? And, second, they want to help teach ways of preserving the body's health and youthfulness. To that end, they've included an "Owner's Manual Diet," a 10-day menu plan designed not for weight loss, but to make you feel "years younger." Its simple recipes are each meant to benefit a certain body system, such as Tomato Bruschetta, packed with the antioxidant lycopene, which has been proven to boost immunity. --Erica Jorgensen

Between your full-length mirror and high-school biology class, you probably think you know a lot about the human body. While it's true that we live in an age when we're as obsessed with our bodies as we are with celebrity hairstyles, the reality is that most of us know very little about what chugs, churns, and thumps throughout this miraculous, scientific, and artistic system of anatomy. Yes, you've owned your skin-covered shell for decades, but you probably know more about your cell-phone plan than you do about your own body. When it comes to your longevity and quality of life, understanding your internal systems gives you the power, authority, and ability to live a healthier, younger, and better life.

You: The Owner's Manual challenges your preconceived notions about how the human body works and ages, then takes you on a tour through all of the highways, back roads, and landmarks inside of you. After taking a quiz that tests your body of knowledge, you'll learn about all of your blood-pumping, food-digesting, and keys-remembering systems and organs.

Just as important, you'll get the facts and advice you need to keep your body running long and strong.
