"If you woke up this morning with a splitting, dull or throbbing headache, you may find some consolation in knowing that your misery had plenty of company. About three out of five people have the common variety and millions of men and women suffer from chronic pain-in-the-head month after month. Although a headache in itself has never killed anyone, it is one of the most annoying of human complaints. What really brought on your agonzing head this morning? Sinus trouble? Something you ate the night before? Lack of sleep? Chances are the underlying reason is the last one you suspect. Medical authorities maintain that the headaches most easily relieved are those that are clearly recognized for what they are. Once you can identify and understand your own brand of headaceh, you may be able to avoid many of those harrowing attacks that interfere with your job, often cause accidents in errors and judgment, and mar your social and family life."
