Researchers at Boston University have identified a kind of genetic signature in people who are likely to live to age 100 or older. The technique may also help doctors predict (1)__________________________, decades before the symptom show up.
Living a long, healthy life tends to run in families. If your grandparents and parents lived into their 90s and remained relatively healthy until the end, there's a pretty good chance you will, too.
So it's pretty clear genetics plays some role in longevity. In this study, the research team developed a new statistical way of analyzing the genetic code of people who had reached age 100 (2)__________________________. Tom Perls, who heads the New England Centenarian Study, explains what they found.
"We discovered 150 or so genetic markers that can highly predict whether or not a person has the genetic propensity to live to extreme old age." Using just that large number of genetic markers, the team was able to predict (3)__________________________.
