![]() Today, the average newborn can expect to reach 80 years. Taking controlĪt the beginning of the 20 th century, the average life expectancy at birth in the United States was just under 50 years. The results were reported in the journal Frontiers in Genetics. This might then allow an extended lifespan. The researchers hypothesize that the genes linked with long life may somehow offset the disease-linked genes. ![]() ![]() more than 50 possible longevity-associated variants in genes, some of which were unexpected and had not been seen before.about the same number of gene variants linked to increased disease risk as seen in people from the general population whose genomes have been sequenced.DNA that appeared to be very similar to people who did not have long lives.In what the researchers describe as the first study of its kind, they analyzed and deciphered the entire genetic codes of a man and a woman who lived past the age of 114. What is it that lets some people live to age 100 and beyond? A new study from the ongoing New England Centenarian Study suggests that protective genes may make a big contribution.
