The nagging nanny of life. Hunger beats on your door reminding you to go on living. Huger will tell you not only that you need to eat but what you need to eat. (There is some evidence, none fully conclusive, that cravings are often good indicators of mineral deficiencies.) In most cases if you listen to your body you will stay healthy, though if you eat so much that you never really feel hunger it can be hard to know what your body is saying.

And, of course, people don’t just hunger for food.
