They say that you can tell how old a tree is by cutting it down and counting the rings. That's true of most trees, but not the magic tree. A magic tree is coy about its age and prefers to hide its rings. All that's left is to guess a magic tree's age, and - as per the adage - a gentleman should never try to guess a magic tree's age. At least guess a few decades younger: they're sensitive to that sort of thing.
