It doesn't matter when or how much a person sleeps, but everyone needs some rest to stay alive. That's what all doctors thought, until they heard about Al Herpin.

　　Al Herpin, it was said, never slept. He was 90 years old when doctors came to his home in New Jersey. They expected to find out that he needed sleep of some kind. But they were surprised. Though they watched him every hour of the day, they never saw Herpin sleeping. He did not even own a bed. He never needed one.

　　The closest that Herpin came to resting was to sit in a rocking chair(摇椅) and read some news papers. The doctors were puzzled by this strange continuous sleeplessness. Herpin offered the only probable explanation of his condition. He remembered some talk about his mother having been injured several days before he was born.

　　From the very beginning, Martin felt that he was bound up with（与……紧紧地在一起）his lovely little patient. One day, following some tests , Betty gave the doctor a big hug（拥抱）.

　　A few months later the doctor removed not only the tumour（肿瘤）, but also the entire lower left side of Betty’s gum（牙龈）and jawbone. Because Betty was so young, Martin was hopeful that her jawbone might regenerate.

　　Within three months, Betty’s tumour grew as large as an orange, changing the natural appearance of the left side of her small, delicate （ = thin; not strong）face. Soon she couldn’t even close her mouth, and as her eating problems worsened, Betty ‘s weight dropped from 20 kilos to 15. Martin knew from experience that it might invade the brain.

　　The only other possibility was thorough radiation therapy （放射疗法）. Night after night, Betty's father gave her injection, but the tumour remained as big as ever. Then one evening. Morgan noticed that the tumour had begun to change. It was actually becoming smaller! For two months her tumour appeared to be going away for ever. In the coming months, Betty’s tumour continued to appear. She was able to eat solid food once again. Her jawbone was regenerating. The tumour was gone.

The vitamins necessary for a healthy body are normally supplied by a good mixed diet, including a variety of fruits and green vegetables. It is only when people try to live on a very restricted diet, say that when trying to lose weight, that it is necessary to make special provisions to supply the missing vitamins.

　　An example of the dangers of a restricted diet may be seen in the disease known as “beri-beri”, which used to make large numbers of Eastern people who lived mainly on rice suffer. In the early years of last century, a Dutch scientist named Eijkman was trying to discover the cause of beri-beri. At first he thought it was transmitted（传播）by a germ（病菌）. He was working in a Japanese hospital, where the patients were fed on polished rice which had had the outer coverings removed from the grain. It was thought this would be easier for weak and sick people to digest.

　　Eijkman thought his germ theory was proved when he noticed the chickens in the hospital yard, which were fed on remains from the patients’ plates, were also showing signs of the disease. He then tried to separate the germ, which he thought was causing the disease, but his experiments were interrupted by a hospital official, who ordered that the rice without coverings, even though left over by the patients, was too good for chickens. It should be recooked for the patients, and the chickens should be fed on cheap, rough rice with the outer coverings still on the grain.

　　Eijkman noticed that the chickens began to recover on the new diet. He began to consider the possibility that eating unmilled rice（糙米）somehow prevented or cured beri-beri — even that a lack of some ingredient（成分）in the coverings may be the cause of the disease. Indeed this was the case. The element needed to prevent beri-beri was shortly afterwards separated from rice coverings and is now known as vitamin B. The milled rice, though more expensive, was in fact causing the disease the hospital was trying to cure. Nowadays, this terrible disease is much less common thanks to our knowledge of vitamins.
