Is There a Cure for Aging?
-
Scientists have studied the immortal jellyfish, Turritopsis dohrnii. It's the only animal that can cheat death by reverting from adulthood back to its polyp stage when threatened with danger or starvation. Other clues to possible eternal life also may exist underwater. Certain marine clams can live more than 500 years. And lobsters stock a seemingly limitless supply of a youthful enzyme that has some scientists wondering if the crustacean, under the best conditions, just might live forever.

@srabanti Among humans, researchers have been studying "super-agers" — people who not only live exceptionally long, but also do so without many of the chronic diseases that plague their peers. That's even though they share some of the same bad habits as everyone else.
