Scientists say they can predict if someone can live longer than average, or die earlier by studying their DNA.
The team of researchers in Scotland has developed a system of points for analyzing the combined effects of genetic variations that affect longevity.
People who are credited to the first 10% of the population can count on ninety years longer than those who scored the lowest 10%, they believe.
The Edinburgh University Edinburgh Institute's experts reviewed genetic data from more than 500,000 people, as well as records of the lives of their parents.
They said that they identified 12 regions of the human genome that have a significant impact on life expectancy, including those not previously reported.
Experts say that DNA-sites that have the greatest impact on life expectancy were those that were previously associated with fatal illness, including heart disease and smoking-related conditions.
Dr. Peter Joshis, an AXA at the institute, said, "If we take 100 people at birth or later and use our life expectancy rating to divide them into 10 groups, then the upper group will live for n'year years longer, lower than average.
The researchers said they hoped to detect genes that directly affect people's age.
If such genes exist, their effects were too small to be detected in this study.
"We found that genes that affect the brain and heart are responsible for most of the changes in life expectancy," said Paul Timmers, a postgraduate student at the Institute.
The research is published in eLife magazine.
