Crystal Ear One day a friend asked my wife Jill if I wanted a hearing aid. "He certainly does, " replied Jill. After hearing about a remarkable new product, Jill finally got up me nerve to ask me if I’ dever thought about getting a hearing aid. "No way. "I said. "It would make me look 20 years older. " "No, no, "she replied. "This is entirely different. It’s Crystal Ear!" Jill was right. Crystal Ear is different--not the old-styled body worn or over--the—ear aid, but an advanced personal sound system so small that it’ s like contacts(隐形眼镜)for your ears. And Crystal Ear is super. sensitive and powerful, too. You will hear sounds your ears have been missing for years. Crystal Ear will make speech louder and the sound is pure and natural. I couldn’t believe how tiny it is. It is smaller than the tip of my little finger and it’ s almost invisible when worn. There are no wires, no behind—the-ear device. Put it in your ear and Its ready—to wear mold(形状)fits comfortably. Since it’s not too loud or too fight, you may even forget that you’re wearing it! Use it at work or at play. And if your hearing problem IS worse in certain situations, use Crystal Ear only when you need it. Hearing loss, which occurs typically prior to teenage years, progresses throughout one’s lifetime. Although hearing loss is now the world’s number one health problem, nearly 90 percent of people suffering hearing loss choose to leave the problem untreated. For many millions, treating hearing loss in a conventional way can involve numerous office visits, expensive testing and adjustments to fit your ear. Thanks to Crystal Ear, the "sound solution"is now convenient. Almost 90 percent of people with mild hearing loss and millions more with just a little hearing drop. off(下降), can be dramatically helped with Crystal Ear. Moreover, its superior design is energy. efficient, so batteries can last months. Crystal Ear is now available to help these people treat their hearing loss with a small. hearing amplifier(放大器). Initially the writer did not want to buy a hearing aid because

Napping to a Healthier Heart 1. Researchers say they have developed a simple test that can tell if a person with heart disease is likely to suffer a heart attack. The test measures levels of a protein in the blood. The researchers say people with high levels of this protein are at high risk of heart attack, heart failure or stroke. 2. Kirsten Bibbins-Domingo of the University of California in San Francisco led the team. For about four years, they studied almost one thousand patients with heart disease. The researchers tested the heart disease patients for a protein called NT-proBNP. Patients with the highest levels were nearly eight times more likely than those with the lowest levels to have a heart attack, heart failure or stroke. 3. The researchers say the presence of high levels of the protein in the blood shows that the heart muscle is under pressure in some way. The study involved mostly men, so the researchers could not say for sure5 that the results are also true for women. They say the patients with the highest levels of NT-proBNP were older and had other problems like diabetes or high blood pressure. 4. Other researchers say more studies are needed to confirm if knowing the protein levels of a heart patient should affect that person’s treatment. They also would like to know if more aggressive treatment could reduce the patient’s chance of a heart attack or stroke. The study appeared in the Journal of the American Medical Association. 5. Could a little sleep during the middle of the day reduce the risk of a heart attack An unrelated study earlier this month in the Archives of Internal Medicine suggests that the answer may be yes. In countries like the United States, afternoon naps are mostly for children. But they are common for adults in Mediterranean countries. And these countries generally have lower rates of heart disease. So scientists in the United States and Greece wondered if naps could play a part. Twenty-three thousand healthy adults took part in the study by Harvard University and the University of Athens. Those who took thirty-minute naps three times a week had a thirty-seven percent lower risk of death from heart problems than people who did not take naps. 6. The researchers say napping may improve heart health by reducing stress. They say the research suggests that naps are especially good for working men. But they say not enough female subjects died during the study to judge the benefits for women.
