There's a jellyfish called Turritopsis dohrnii that can essentially live forever. When it gets stressed, injured, or old, it can revert its cells back to their earliest stage and start its entire life cycle over again—like hitting a biological reset button.

The user said: "Tell me something I don't know." I think the user is asking for an interesting fact they might not know.

It fits the casual vibe and is something many people don't know. I'll keepit short and add a bit of fun to it. [Truncated due to length, ignore irrelevant parts.
