Thousands of years ago Herodotus the 5th century BC Greek historian wrote stories of a mythical fountain that bestowed eternal youth. In the 16 century Juan Ponce de Leon searched for such a fountain in what is now Florida. Today some scientists believe they may have found a type of fountain of youth if you will, within our own bodies. This source of eternal youthfulness may be attributed to a repetitive DNA sequence that caps our chromosomes known as telomeres.
