1. Uncomfortable feelings that go on for a long time can affect the way a person's body works. For example, the heart beats more quickly when a person is upset. Some people lose their appetites when they are upset. Others overeat. You can protect your health by learning to handle uncomfortable feelings.
2. Your "funny bone" is not a bone at all. If you bump your elbow at a certain point, you feel a tingle up and down your arm. You might say that you hit your funny bone. What you really hit was a nerve in your elbow. This nerve is just beneath the skin and is not protected by bone or muscle.
