To my family

I was running through the woods at full speed when my right foot made contact with a large tree root jutting out of the ground in front of me. My running partner was ahead of me and, thankfully, out of sight, so he didnt see me stumble. We were almost done; only a few more turns on the winding dirt path wed been following for the better part of five miles and we would be at the car.

I struggled to stay upright, but I couldnt. It was impossible to keep my feet under me. My view of the trees turned sideways and I went down. My hands landed first, followed by my right arm, and then the rest of my body with a loud thud. Everything stopped moving for a few seconds before I could manage to make sure that I was still in one piece. With only a small amount of blood trickling down my leg, I jumped to my feet and was off again. My heart beat loudly in my ears, and my labored breathing reverberated in my chest, but I was moving again and could see my running mate in the distance. A few turns later, the dark greens and browns of the woods gave way to the sun reflecting off the cement parking lot where a lone blue BMW sat parked at the far end. Rolf, my running partner, was already toweling himself off and drinking from a water bottle he had stashed in the car. I had made it. As I walked over to him, I straightened up even more in order to shake off and hide the pain I was in, put on my best smile, and tried to look as confident as possible.

Its always a little nerve-wracking going for a run with someone you dont know, and even more so when your running partner is deciding whether he wants to offer you a job. A week earlier I had received an email from Rolf Zwaan, a professor at Florida State University, where I was about to interview for my first big-time assistant professor position. Rolf asked whether I wanted to go for a run with him in Elinor Klapp-Phipps Park, a nearby nature preserve, the night before my interview started. My plane got in early, so it would be something to do to pass the time, he suggested. To be honest, my first thought was Absolutely not. Did I really want to spend any more time than I had to with someone who was going to be judging my every move for the next two days? But the more I thought about the idea, the more appealing the run became. Interviewing for a job is a rather sedentary experiencesitting in meeting after meeting all day longso any opportunity to get in a workout seemed like something I shouldnt pass up. Pumping up my body always seemed to do something positive for my mind, and being outdoors made me feel sharper. As the poet and essayist Ralph Waldo Emerson wrote, The health of the eye seems to demand a horizon. We are never tired, so long as we can see far enough. And finally, I hoped during our run to learn more about the cool research Rolf had been doing.

Rolf was trying to understand how humans think. I had just read a paper of his in which he argued that we dont think the

Rolfs work points to a new way to think about thinking: it demonstrates that our thinking is embodied in that it involves re-experiencing similar bodily experiences from the past. This means that our brain might not make a clear distinction between past memories and what we experience in the present. In other words, our neural hardware might not draw a clear division between thought and action, so that we might be able to use our body and our physical environment to be sharper mentally.

The day after our run in the park, I couldnt help but consider all the factors that would contribute to whether I was going to ace my interview. I realized that lots of influences outside my own cortex affected the thought processes that went on inside it.

This book is about the many external influences that affect the contents of our mind. The ways my brain worked in my interview, for instance, were influenced by my run the day before. Yes, the exercise made my thoughts sharper, but simply being in the woods had changed my thinking too. And holding my body as if I werent in pain after my fall actually made me feel better. Whatever webabies, kids, adults, athletes, actors, CEOs, and youdo from the neck down has a striking impact on what goes on from the neck up. From our brains standpoint, there isnt much of a line between the physical and the mental. This book explains how we can take advantage of that permeable line and improve our mind by using our body.

Today countless books detail how we think and reason, from Dan Arielys Predictably Irrational to Daniel Kahnemans Thinking Fast and Slow . However, very few books consider the influence that our body has on our thinking and decision making, or, more important, how we can leverage our body to change our own mind and the minds of those around us. We tend not to give our body much credit for how we think and feel. But, simply put, kids learn better when they can freely use their body as a tool for acquiring information. For instance, practicing printing letters actually helps kids read. And when you relate mathematical concepts in physical terms, like Add money to your piggy bank or Give away half of your cookies to your sister, kids better understand numbers. The tight relationship between body and mind is also why music and mathematical talent often go hand in hand. Our ability to control our finger movements and our ability to juggle numbers in our head share common neural real estate, which scientists have argued is one reason why building finger dexterity through piano playing can help kids count more fluently in math.

As students test scores are emphasized more and more, administrators are cutting music, recess, and play in order to keep kids confined to their chairs. But this is a terrible policy, since children learn best through action. How we think is intimately tied to our body and our surroundings. Random hands-on activities cannot make up for our educational woes and our slipping global standing in math and reading skills, but realizing that the body shapes the mind gives us power to structure school to help children learn and think at their best. The current schooling regimen actually hinders childrens thinking and learning. In fact our current, sedentary office workplaceand our sedentary lifestylekeeps adults from thinking and performing at their best too.

The ancient Greeks viewed the human body as a temple that houses the mind. They recognized the linked health of mind and body. By extension, its also important to pay attention to the environment in which you place your body. Ill tell you the mental power that exercise gives you and show you why body-centered meditation can enhance your ability to focus at work. You will also meet a researcher who has discovered that green space in inner-city projects leads to less violence in the home. And you will learn how to use the power of nature to think more clearly and have more self-control.

Your body helps you learn, understand, and make sense of the world. It can influence and even change your mindwhether or not you are aware of its influence. Companies that make health care products, snacks, and beverages, like Johnson & Johnson and Coca-Cola, have figured this out; they use scientific information about the bodys influence to convince us to buy their products. Companies like Google, which understand how important our body is to thinking and creativity, make it easy for their employees to get up and move and to get out and exercise. When your body can move outside the box, your thinking tends to follow.
