# Summary

```Since birth, you've wanted to discover things. You started out by putting every available object in your mouth. Later you began asking the grownups all those "why" questions. None of this makes you unique — humans are naturally curious animals. What's unusual is that you've decided to take a physics course. There are easier ways to satisfy a science requirement, so evidently, you're one of those uncommon people who has retained the habit of curiosity into adulthood, and you're willing to tackle a subject that requires sustained intellectual effort. Bravo!

```“A remarkable book, which in an entertaining way takes a deep dive into our bodies . . . you’ll never see (or taste) food the same way again!” —Martin Lindstrom, New York Times–bestselling author

A Belgian chocolate cake topped with a velvety homemade mousse catches your eye on the menu. The next thing you know, you’ve ordered it—despite the hefty price. But do you know why?

Through over 40 compelling questions, this book explores how our eating decisions tread the line between conscious and subconscious, and enables us to be more intelligent about food. With expert insights that draw from psychology, neuroscience, popular culture, and more, learn to see the innumerable influences behind your diet and cravings—from the size and color of your plate, to the placement of products in a supermarket, to the order in which you sit when out with friends.

And the chocolate cake? Would you believe research shows that regional descriptions (Belgian!) and emotive, sensory language (homemade! velvety!) subtly affect your appetite? Know what and why you eat, when and how you do—before you next sit down to dine.

“We make 200 conscious and unconscious decisions about food every day. Clearly, eating is no fun anymore. The authors want to cut through the juice cleanses and paleo diets to bring back some common sense.” —The New York Times Book Review

“The connections between our emotions and the foods we choose are explored in fascinating detail.” —Parade.com

```“The stories are skillfully told and entirely entertaining . . . An expert, mostly feel-good book about modern medicine” from the award-winning author (Kirkus Reviews, starred review).

Behind every landmark drug is a story. It could be an oddball researcher’s genius insight, a catalyzing moment in geopolitical history, a new breakthrough technology, or an unexpected but welcome side effect discovered during clinical trials. Piece together these stories, as Thomas Hager does in this remarkable, century-spanning history, and you can trace the evolution of our culture and the practice of medicine.

Beginning with opium, the “joy plant,” which has been used for 10,000 years, Hager tells a captivating story of medicine. His subjects include the largely forgotten female pioneer who introduced smallpox inoculation to Britain, the infamous knockout drops, the first antibiotic, which saved countless lives, the first antipsychotic, which helped empty public mental hospitals, Viagra, statins, and the new frontier of monoclonal antibodies. This is a deep, wide-ranging, and wildly entertaining book.

“[An] absorbing new book.” —The New York Times Book Review

“[A] well-written and engaging chronicle.” —The Wall Street Journal

“Lucidly informative and compulsively readable.” —Publishers Weekly

“Entertaining [and] insightful.” —Booklist

“Well-written, well-researched and fascinating to read Ten Drugs provides an insightful look at how drugs have shaped modern medical practices.  Towards the end of the book Hager writes that he ‘came away surprised by some of the things he had learned.’  I had the very same reaction.” —Penny Le Couteur, coauthor of Napoleon’s Buttons: How 17 Molecules Changed History```

`“An engaging and complex examination of the development of the human brain throughout its evolutionary history” (Publishers Weekly).   After several million years of jostling for ecological space, only one survivor from a host of hominid species remains standing: us. Human beings are extraordinary creatures, and it is the unprecedented human brain that makes them so.   In this delightfully accessible book, the authors present the first full, step-by-step account of the evolution of the brain and nervous system. Tapping the very latest findings in evolutionary biology, neuroscience, and molecular biology, Rob DeSalle and Ian Tattersall explain how the cognitive gulf that separates us from all other living creatures could have occurred. They discuss   • The development and uniqueness of human consciousness • How human and nonhuman brains work • The roles of different nerve cells • The importance of memory and language in brain functions, and much more   Our brains, they conclude, are the product of a lengthy and supremely untidy history—an evolutionary process of many zigs and zags—that has accidentally resulted in a splendidly eccentric and creative product.`
