At least, so it's said:
"Researchers at Harvard Medical School may have deciphered an aging process that applies to everything from yeast to mice to humans. A group of genes called "sirtuins", which regulate gene activity in cells and repair DNA breaks, over time become so busy with increasing DNA repairs that their regulating duties suffer; that's when traits of aging appear. But when scientists added copies of sirtuin to mice subjects or stimulated the gene's activity, the mice's lifespan increased by 24 to 46 percent. "Our hypothesis was that with more sirtuins, DNA repair would be more efficient, and the mouse would maintain a youthful pattern of gene expression into old age," says lead author Philipp Oberdoerffer.
Researchers say that based on their findings (published in the journal Cell), aging may one day be reversible"
