Researchers at Boston University have identified a kind of genetic signature in people (1)_________________________________. The technique may also help doctors predict whether you're likely to get a disease, 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 (2)_________________________________, 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 as compared with people who had a more typical lifespan. 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, (3)_________________________________.
