There is talk about how old Tom is and how old Treebeard is, but how old do you think Gandalf is? He seems to have been around forever too. I mean you can't even kill the guy. He reminds me of a Dr. Who character that continues to exist. Never in the book do they mention that Gandalf is human. When they mention the humans in the company they name Borimir and Aragorn.
While we are at it, how old do you think Aragorn is? The books talk about things that he done 38 years ago. Is Aragorn 50 plus years old when all of this is taking place? This reminds me of Beowulf fighting a dragon at age 70. Aragorn could be 70 too. How long exactly does a Numenorian live?
