Exercise and diet are always important parts of ensuring a long and healthy life. However, it's starting to look more and more like certain people are just born with the genes to live past 100. You've either got 'em or you don't. Researchers across the world are sifting through the volumes of human genetic information to try and pinpoint longevity genes. A key part of their efforts is studying the genetic makeup of the mere 79 men and women who are alive today and over the age of 110. If scientists can isolate the genes that lead to longevity you'd better start planning to save a lot more for retirement.
