Much more interest has been shown in preventive medicine in recent years. This is probably due in part to the increasing costs of medical treatment, but the writings of such people as Dr. Keneth Cooper have also played an important role. In his book Aerobics. Dr. Cooper communicated his message of the benefits of exercise so effectively that many other authors have flowed in his trail, and literally millions of readers have put on their sports shoes and taken to the highways and byways of America. A recent survey showed that over 17 million people are jogging. Many of these are so serious that they have trained themselves to run the 26 miles and 385 yards of the hard and tiring marathons that are sponsored all over the country. The last time I was in Honolulu, I was amazed to see hundreds of people, young and old, running for their lives, and I discovered many of them have run in the Hawaiian Marathon. Exercise has also become a major part of conversation. A1 a dinner party recently, the president of a bank asked me, "You look like a runner; how far do you run each day？" A few days later when I appeared on a national television show, the host suddenly asked me if I was a regular runner. On both occasions the conversation turned to the subject of exercise and I found, as I have found whenever I have traveled recently, that this is a subject on many people's minds. Of course, there are still many people who are less than enthusiastic about exercise. They appreciate the philosophy of Robert M. Hutchins who said, "Whenever the thought of exercise occurs to me, I lie down till it passes." The first paragraph indicated that medical workers ______. A．are in great demand？ B．make a lot of money C．are concerned with their own health D．like sports more than ordinary people
