Author Philip Roth once wrote that "old age isn't a battle. It's a massacre." It's obvious when you think about it.
Although people have been living longer, and staying fitter while doing so than ever thanks to increasing focus on diet, exercise, and all kinds of lifestyle choices, time is always going to win.

But, fight it all you want, time holds all the cards and all the ailments it brings tend to gang up on you.
Of course, that hasn't stopped scientists from looking for better ways to hold off that massacre. Now, researchers at Tel Aviv University say they've come up with a method that really does turn back the clock.
