National Geographic on Longevity - ethnic markers explain a lot of the headline news

In this month's National Geographic there is a good article on the progress being made identifying the genetic markers for centenarians. As the life settlement market wakes up to the fact that an 80 months life expectancy is not equal to another 80 months life expectancy, we also get to the politically incorrect statements that certain genetic markers are more prevalent in certain ethnic communities. Now that these statements come from the National Geographic, we can more easily deal with longevity markers in the Ashkenazi Jewish and Japanese American population. It has not been made explicit - but a Japanese born and bred male emigrating to and living in the US and a US-born male of Japanese descent have quite different longevity profiles. Longevity is micro, case by case !
