For example, gene modification that uses the longevity genes from giant tortoises is one way to extend life. "However, there is also a method that is akin to a rebirth. You know jellyfish, right? There are more than 200 species of them in the ocean. Most jellyfish die after reproducing, but there's one species called the immortal jellyfish. "The life cycle of the immortal jellyfish includes stages from a fertilized egg to larva, then polyp, and finally adult jellyfish.

It then grows back into a jellyfish and can repeat this cycle as long as it avoids being eaten by other creatures. "If we could incorporate this phenomenon into human genes, it cou
