“After a stressful event, we often crave comfort food. Our body is calling for more glucose and simple carbohydrates and fat... And in modern life, people tend to have fewer friends and less support, because there's no tribe. Being alone is not good for the brain.”

“The essence of physical education in Naperville 203 is teaching fitness instead of sports. The underlying philosophy is that if physical education class can be used to instruct kids how to monitor and maintain their own health and fitness, then the lessons they learn will serve them for life. And probably a longer and happier life at that. What's being taught, really is a lifestyle. The students are developing healthy habits, skills, and a sense of fun, along with a knowledge of how their bodies work. Naperville's gym teachers are opening up new vistas for their students by exposing them to such a wide range of activities that they can't help but find something they enjoy. They're getting kids hooked on moving instead of sitting in front of the television.”

“One small but scientifically sound study from Japan found that jogging thirty minutes just two or three times a week for twelve weeks improved executive function. But it's important to mix in some form of activity that demands coordination beyond putting one foot in front of the other.... Aerobic exercise and complex activity have different beneficial effects on the brain. The good news is they're complementary.”

“Exercise is not an instant cure, but you need to get your brain working again, and if you move your body your brain won't have any choice.”
