Secret of a long life span

“How to get a long and healthy life span?” has been one of the most concern topics for all human beings. Scientists have now explained why some people can have their life span over a century. It’s widely believed that a gene called FOXO3A holds the genetic material that allows humans to live a long and healthy life. Out of the study, most of the men who participated had letter T at the key location along the identified genetic coding. However, the other participants who had letter G encoded at the key location doubled their chance of living old and healthy, and similarly those who had two G copies further increased their chance to triple. In term of healthy life, those who had G copies showed less heart diseases, stroke and cancer.
