4. If a small piece of food (for example, a peanut) starts to "go down the wrong way" into your lungs, then you will start to cough. Coughing will bring the food back up - and may save your life.
5. Your brain contains a remarkable appetite-control centre, which is designed to make sure that you eat the right type and the right amount of food. Many of us become fat and unhealthy because we ignore our body's needs. You can stay healthy - and slim - by learning to 'listen' carefully to your body. Eat when you are hungry, and stop eating when you are full. Grandmother's advice to "eat a little of what you fancy" was quite sensible.

7. Your body contains a thermostat which is designed to help keep your body's internal temperature stable - whatever the outside temperature may be. If the weather is hot, then you'll sweat and lose heat. If the weather outside is cold, you'll shiver, and the involuntary muscle movement will build up your internal temperature.
Obviously, we all need outside help occasionally. If you break your leg, then you'll need help from the professionals.
