People who score in the top ten percent of the population might expect to live up to five years longer than those who score in the lowest ten percent, found study.

‘The DNA sites with the greatest impact on overall lifespan were those that have previously been linked to fatal illnesses, including heart disease and smoking-related conditions.’

People who score in the top ten percent of the population might expect to live up to five years longer than those who score in the lowest ten percent, they say. 




The findings also revealed fresh insights into diseases and the biological mechanisms involved in ageing, the researchers say.
Experts at the University of Edinburgh's Usher Institute looked at genetic data from more than half a million people alongside records of their parents' lifespan.
Some 12 areas of the human genome were pinpointed as having a significant impact on lifespan, including five sites that have not been reported before.
Genes that have been linked to other cancers, not directly associated with smoking, did not show up in this study, however.

The researchers had hoped to discover genes that directly influence how quickly people age. They say that if such genes exist, their effects were too small to be detected in this study.

Dr Peter Joshi, an AXA Fellow at the University of Edinburgh's Usher Institute, said: "If we take 100 people at birth, or later, and use our lifespan score to divide them into ten groups, the top group will live five years longer than the bottom on average."
Paul Timmers, PhD student at the Usher Institute, said "We found genes that affect the brain and the heart are responsible for most of the variation in lifespan."
