Is age the cause of receding gums? By Claudia Hammond.
The phrase “long in the tooth” comes from the practice of gauging a horse’s age by the length of its teeth. Nineteenth century horse-traders were not a particularly trustworthy bunch, so a wise buyer would often check inside the animal’s mouth. If the teeth looked long it meant its gums had already receded, suggesting the potential purchase might be older than claimed. This might have served people well when it came to buying horses, but what about humans? Gingival recession, as it’s formally known, is more common amongst the elderly. A US study of almost 10,000 people found that 38% of people aged 30-39 had some degree of the condition, compared with 71% in the 50-59 age group, and 90% for those aged between 80-90. However that doesn’t mean ageing in itself is the cause. It’s a long process that can start in your teens, and one that can be triggered by various factors. In some cases, there is nothing people can do to reduce their chances of developing the condition. Some people inherit thin and fragile gums which recede more easily. Others have teeth which are overcrowded or stick out, meaning that there’s not enough jawbone to cover the root of the tooth. Dental hygiene also plays a big role. Plaque, consisting of a sticky film of bacteria, is constantly forming on our teeth. Failure to clear the build ups through brushing and flossing can lead to gum disease. If left untreated, one possible complication is the destruction of the bone around the teeth and the gum tissue in which they sit. As the tissue recedes, the root of the tooth is exposed, making it appear longer. Then there’s the way you brush your teeth. If you use a sawing action with a hard brush, there’s a danger of gradually wearing away the gum. For this reason dentists tend to advise brushing in small circles with a soft brush or using an electric toothbrush to prevent you from pressing so hard. The damage accumulates over time, causing the gums to recede imperceptibly, until one day you look in the mirror and realise you’ve changed. As this transformation can take decades, many people assume it’s a natural part of the ageing process. Research on receding gums often relies on asking people what kind of toothbrush they use, the brushing motions they use and how hard they brush. Some argue that due to a lack of controlled studies, there’s no definitive evidence that hard brushing does anything more than cause temporary abrasions, but many dentists do consider there to be a link. The condition is also more common in smokers. With so many different factors involved, controlled studies are difficult to do. Many are cross-sectional, meaning they take a snapshot in time. So if you’re looking to buy a horse it might be worth their checking their teeth, but ageing is not a direct cause of receding gums. It’s simply that the damage accumulates and becomes more obvious over time. Source: http://www.bbc.com (Adapted)
According to the text, judge the items below as true (T) or false (F).
I. Nineteenth century horse-traders were reliable people. II. A buyer who would check the horse's gums before buying it, was not considered a clever person. III. Although it is more observed amongst the elderly, gingival recession can begin during youth. IV. The phrase “long in the tooth” is related to the practice of determining a horse's age, and therefore its value, by examining its teeth. V. People can always prevent the development of gingival recession, once it is never possible for them to inherited sensitive gums.

Whaling Today
By Meghan E. Marrero and Stuart Thornton
Tuesday, November 1, 2011

     In 1946, several countries joined to form the International Whaling Commission (IWC). The IWC’s purpose is to prevent overhunting of whales. Its original regulations, however, were loose, and quotas were high. Whale stocks continued to decline. The IWC eventually established whaling-free sanctuaries in the Indian Ocean (1979) and the ocean surrounding Antarctica (1994).
    The IWC called for a moratorium on commercial whaling in 1982. Both Japan and Norway voted against this policy. Today, Norway supports hunting minke whales for meat. Japan allows whaling for scientific purposes, although many experts question if more whales are taken than are necessary. Meat from whales killed for research is sold as food. 
     Many species of whale have benefitted from the IWC’s moratorium. Dave Weller, a research biologist at NOAA’s Southwest Fisheries Science Center in La Jolla, California, says the eastern Pacific gray whale population has recovered.
     “I think there is pretty good evidence that a moratorium on hunting has allowed certain populations to recover from depleted status when they were being whaled,” he says.
     According to Weller, the IWC’s moratorium on whale hunting is one of two major steps the organization is taking.
     “The other thing that the IWC has very successfully done is to collect information and provide analysis of data to help us understand the status of various populations that in some cases we knew very little about,” he says.
      Despite the general moratorium, limited whaling is permitted to indigenous cultures.
     “In the United States, the Inuit Eskimos in the north slope of Alaska, in Barrow, Alaska, still hunt for bowhead whales,” Weller says. “There is a request by the Makah Indian tribe, which is in northern Washington state, to resume gray whale hunting, which they had traditionally done. But that’s pending deliberations right now.”
