What is the longest living playable race in DnD?

I'm curious, what is the longest living playable race in the world of Dungeons and Dragons? Are there any races that are known for their longevity and ability to survive for centuries or even millennia? And if so, what are their unique characteristics and abilities that contribute to their longevity? It would be fascinating to learn more about the history and lore behind these races and how they fit into the broader DnD universe.
