Article: In the Caucasus region of Russia, nearly 50 out of every 100,000 people live to celebrate their 100th birthday, and many don't stop at 100! By comparison, in America only 3 people in 100,000 reach 100. But these Russian old people aren't alone. The Pakistanis, who live high in the Himalaya Mountains, and the Ecuadorans of the Andes Mountains seem to share the secret of long life, too. These people remain healthy in body and spirit despite the passage of time. While many older persons in industrial societies become weak and ill in their 60s and 70s, some Caucasians aged 100 to 140, work in the fields beside their great-great-grandchildren. Even the idea of aging is foreign to them. When asked "at what age does youth end?"most of these old people had no answer. Several replied, "Well, perhaps at age 80." What accounts for this ability to survive to such old age, and to survive so well?First of all, hard physical work is a way of life for all of these long-lived people. They begin their long days of physical labor as children and never seem to stop. For example, Mr . Rustam Mamedov is 142 years of age. His wife is 116 years old. They have been married for 90 years. Mr. Mamedov has no intention of retiring from his life as a farmer. "Why?What else would I do?"he asks. All these people get healthful rewards from the environment in which they work. They all come from mountainous regions. They live and work at elevations of 1,660 to 1,000 meters above sea level. The air has less oxygen and is pollution-free. This reduced-oxygen environment makes the heart and blood vessel system stronger. Another factor that may contribute to the good health of these people is their isolation. To a great extent, they are separated from the pressures and worries of industrial society. Inherited factors also play some role. Most of the longest-lived people had parents and grandparents who also reached very old ages. Good family genes may, therefore, be one factor in living longer.
Answer: are still working in the fields
The example of Mr. and Mrs. Mamedov implies that some Caucasians aged 100 to 140 _ .

Article: On Jan. 13th, 2009, the Peanut Corporation of prefix = st1 /Americaissued a recall for products it had made over the past six months, after five people had died and more than 400 had fallen ill with salmonella poisoning as a result of contamination. Two weeks later, the recall was extended to more than 400 consumer products made since Jan. 1, 2007, including Jenny Craig nutritional bars and Keebler Peanut Butter Sandwich Crackers, while the toll from the contamination had reached eight dead and more than 500 sickened in 43 states, half of them children. The company's factory in Blakely,Ga., which was the source of the contamination, supplied some of the largest food makers in the nation. The outbreak showed the complexities of the industrial food chain, and left consumers to figure out if some food in their cabinets had a danger. The recall of peanut products is the latest in a series of increasingly severe food contamination scares involving tomatoes, spinach, cantaloupes and other foods. TheGeorgiaplant, which is closed, packed peanut butter in bulk ranging from 5 to 1,700 pounds, much of which was shipped to institutions. Many school districts have pulled peanut butter from menus, with some substituting more commonly recognized supermarket brands. New York City school officials said they had not bought any peanut butter or products with ingredients that originated at theGeorgiaplant. An F.D.A. inspection team that visited the plant on Jan. 9 discovered that on 12 occasions in 2007 and 2008 tests conducted by the company found salmonella contamination in its products but that it shipped the contaminated products to customers after a retest found no contamination and did nothing to clean the plant.
Answer: people may now worry about the food at their homes.
We can learn from the passage that _ .
