“Serendipity is very important in scientific endeavors and played a critical role in the discovery of the mammalian gene, Klotho.  Mouse and human genetic studies indicate that Klotho may largely determine how intelligent we are, what diseases we are susceptible to and how long we will live.  Injection of synthetic Klotho hormone into mice reduces injury and promotes healing in kidney failure, shrinks tumors in various cancers and ameliorates many of the diseases of aging, including loss of cognition.  Will these therapeutic effects translate into people and allow us to live well longer?”
