BU researchers believe that many of those who live a very long life (into their late 90s) have some genetic variances to thank for the extra years. The scientists, lead by Paola Sebastiani at the School of Public Health and Thomas Perls at the School of Medicine, have found 150 genetic markers that predict with 77 percent accuracy whether people will live extremely long lives, which they defined as late 90s or older. In the United States, where the average life expectancy is 78, only one in 6,000 people make it to 100.
