Genetic test can predict if you'll live to 100
SCIENTISTS claim they can predict whether someone will live to 100 with up to 85pc accuracy after developing a genetic test for healthy ageing.
Researchers came up with the complex formula after studying the DNA of centenarians and identifying common genetic variations which may have contributed to their longevity.
They found a series of markers which appeared to have made people genetically predisposed to a long and healthy life, for example by helping to delay or prevent the onset of age-related diseases such as heart disease and dementia.
These genes could help explain why living beyond 100 appears to run in families, despite the importance of factors such as smoking and diet on our long-term health.
The test is between 60 and 85pc accurate, depending on the subject's age; and is most reliable late on in life, meaning it is unlikely to be useful as an early predictor of an individual's lifespan.
Its ability to pick out long-lived groups who share certain genes could be useful to scientists hoping to find new treatments for age-related conditions. (© Daily Telegraph, London)
