While the average life expectancy beklenti; bekleme in America is 78, it is not unusual to see people living well into their 90s. Each generation nesil seems to add a few years to the natural life span süre and eventually sonunda, with the aid of modern medicine, it is conceivable akla uygun that centenarians asırlık kimse will be the rule rather than the exception istisna. Until that time, however, your genes may be able to predict ummak which side of the century mark your fate kader lies.
Extensive geniş research on the genetic signposts işaret levhası found in long-lived individuals birey, published today in the journal Science, may just be able to provide sağlamak a strong likelihood olasılık of our chances to reach the magic 100 marker. By analyzing 150 signposts, the research team from Boston University was able to construct kurmak a mathematical model, a scientific scorecard to calculate longevity uzun ömürlülük..
In the largest study of its kind, the genomes genom of over 1,000 centenarians were scanned and compared to the genomes of randomly rasgele selected individuals. They were able to identify those genetic markers that were distinctly açıkça different. They then tested the their theory by comparing these specific belirli markers with previously önceden untested centenarians and "achieved an accuracy doğruluk rate of 77%,' according to lead researcher Paola Sebastiani, a professor of biostatistics at Boston University.
Dr. Sebastiani said that the "genetics is fundamental temel in exceptional longevity it's not the only thing.... So there may be other factors like environment or other lifestyles that may help people live longer and healthier lives." Which helps to explain the error rate of 23%.
Only about 1 in 6,000 reach the age of 100 in industrialized countries, and most of them remain kalmak healthy and free from disability sakatlık well into their nineties.
