Fact. You want what they're having, right? There are certain animals out there that don't die from old age simply because they're not designed to. They'll die from predators or from substances that humans have thrown into the oceans without thinking of the wildlife, etc. Jellyfish, hydra and some flatworms therefore won't die. So would you rather be the jellyfish that stings you or would you rather pee on yourself after having been stung by a jellyfish? The grass always seems greener...
