Metal Motors and Jiuman Hearts Hour after hour news was anxiously awaited. It seemed incredible that a man could fly 3,610 miles without stop ping. Could any motor stand such a test? . . . But two motors carried that plane to France. One of metal, the other-the most wonderfully designed motor in the world-a human heart. LIKE the metal motor, the human motor must keep going. When the human motor starts to "miss" and then stops, life's flight is ended. Yet, oftentimes, with no atten tion and more abuse than was ever given any motor invented by man the heart "carries on". Even when damaged or diseased it carries a heavy load-an overload-with little complaint. Whether defective at birth or damaged by dis ease, it keeps at work-day and night-doing its best to make a brave "non-stop" record. Strong hearts need rest and intelligent protec tion. Weak hearts must have their loads lightened or they will be forced to give up. Thanks to modern science everybody can find out how big or how little a load of work, strain and exercise his heart can carry. Briefly, while there are many different kinds of heart difficulties, they may be roughly divided into three general groups. First, the heart troubles of young people caused by diseases of childhood. Rheumatic fever and rheumatism (associated with "growing pains", tonsillitis, and stiff and painful joints) cause heart disease. According to some experts, diphtheria, scarlet fever and measles may injure children's hearts. Second, heart diseases of middle-aged people re sulting from syphilis, or focal infection in teeth, tonsils, sinuses or elsewhere. Third, heart ail ments of old people ultimately resulting from these and from many other causes, including unhygienic living habits. Many persons have defective hearts without realizing the fact, but there are many others who suspect that they have heart trouble when they are suffering from a different cause. There need be no guess work. Know your own heart. Have your doctor examine it regularly. If it is normal and strong, do not shorten (\ its term of usefulness by over strains or excesses. Ifitis damaged or weakened, live in accordance with your doctor's advice. Give your heart a fair chance. Take care of it so that it will carry you safely on a "non-stop flight" to a happy old age. ( 5- I I Heart disease is now the chief of the captains of death. It has risen to this position in the past twenty-five years, surpassing tuberculosis, pneu monia and other diseases. The danger of dying from a bad heart has increased every year, while that from most other deadly diseases has de creased. Under present conditions, one in every five will ultimately die of heart disease in one form or another. The increase in the deathrate from this disease in recent years has been primarily in middle life and at the older ages. While the great majority of those who succumb are relatively old people, there are altogether too many young ones. One out of every seven who dies from heart disease passes away before the age of 45. Physicians, statisticians and others who are studying heart disease suspect that much of it is induced by the hurryingmode of life so general in this country. The Metropolitan Life Insurance Company has prepared a pamphlet entitled, "Strong Hearts" which sets forth the principal facts about this disease. It may be the means of saving you from serious trouble. A copy will be mailed free by our booklet department. Send for it. HALEY FISKE, President.
