research was carried out at Edinburgh University's Usher Institute, involving analysis of 500,000 DNA samples from people of European ancestry in Europe, the UK and the United States.

While most people were found to have roughly the same life expectancy, the top and bottom ten percent of the population can expect to live for five more (or fewer) years based on DNA alone.

Dr Peter Joshi said and I quote "The way statistics work, you have a clearer lens the more people you have in the sample,". "This time we showed that a gene that affects which blood type you are - A or B or O - affects how long you live. Another gene, insulin-like growth factor, appears to affect how you age."
