In a study, old mice become young again and vice versa

In Boston research facilities, aged, blind mice have regained their vision as well as younger, wiser, and healthier muscle and kidney tissue.

According to anti-aging expert David Sinclair, professor of genetics at the Blavatnik Institute at Harvard Medical School and co-director of the Paul F. Glenn Center for Biology of Aging Research, the experiments demonstrate that ageing is a reversible process that can be pushed "forwards and backwards at will." On the other hand, young mice in the study have aged prematurely, with disastrous effects on almost every tissue in their bodies.

Sinclair, the principal author of a recent study showing the findings of his team and other worldwide scientists, claimed that our bodies have a backup copy of our youth that may be activated to rejuvenate.

The combined studies, which were published for the first time on Thursday in the journal Cell, cast doubt on the theory that genetic mutations weaken our DNA as we age, resulting in a junkyard of damaged cellular tissue that can cause degeneration, illness, and death. At Life Itself, a health and wellness conference, Sinclair stated that "it's not junk, it's not harm that causes us to get old."
