<ul><li>We don't have one brain in our head—we have three. We started 
with a “lizard brain” to keep us breathing, then added a brain like a 
cat’s, and then topped those with the thin layer of Jell-O known as 
the cortex—the third, and powerful, “human” brain.</li><li>We were not the strongest on the planet but we developed the strongest brains, the key to our survival. The strongest brains survive, not the strongest bodies. Our ability to solve problems, learn from mistakes, and create alliances with other people helps us survive.</li><li>Our ability to understand each other is our chief survival tool.</li></ul>

•Our brains were built for walking - 12 miles a day !• To improve your thinking skills, move.• Exercise gets blood to your brain, bringing it glucose for energy and oxygen to soak up the toxic electrons that are left over. It also stimulates the protein that keeps neurons connecting.• Aerobic exercise just twice a week halves your risk of general dementia. It cuts your risk of Alzheimer’s by 60 percent.

An updated and expanded edition of the international bestseller Most of us have no idea what’s really going on inside our heads. Yet brain scientists have uncovered details that every business leader, parent, and teacher should know — for instance, that physical activity helps to get your brain working at its best. How do we learn? What do sleep and stress do to our brains? Why is multitasking a myth? Why is it so easy to forget — and so important to repeat new information? In Brain Rules, Dr John Medina, a molecular biologist, shares his lifelong interest in brain science, and how it can influence the way we teach our children and the way we work. In each chapter, he describes a brain rule — what scientists know for sure about how our brains work — and offers transformative ideas for our daily lives. In this expanded edition — which includes additional information on the brain rules and a new chapter on music — you will discover how every brain is wired differently, why memories are volatile, and how stress and sleep can influence learning. By the end, you’ll understand how your brain really works — and how to get the most out of it.
