How old is the oldest living tree?

The answer is: 4,855. Not only have we identified the oldest living tree, but we even gave it a name and put it under witness protection. Methuselah is estimated to be 4,855 years old, meaning it’s been around since 2833 B.C.! Imagine living for that long being stuck in the same place. Even if it wanted you to, you couldn’t put this geezer out of its misery since its location is kept top secret.Source
