well lets see hears a thought for you all to ponder on or laugh at (its meant to be humorous) Gandalf was a pretty old dude in his own right so heres the thing if he were ...hold on i want to word this right....ok...because he died and came back does he have to start over at one or is he still old?
my money is on treebeard...gandalf doesnt exaggerate and he knows tom so its not like he blindly says treebeard is the oldest...we of course must assume we are talking about phytsicly the oldest bombadil is essentially a spirit so its unfair to try him against a physical being
