Wanna join a friend group? A fellowship of likeminded people, if you will? These are the kinds of facts a party needs.

Are you saying Frodo's 18 in the movies this whole time?

I was going to say... I don't think we actually know how old Legolas is. Galadriel is something like 8,000+ years old though so it's not that far fetched.

Granted this is the movies, but wasn't Legolas at the Last Alliance where Isildur cut the ring of Sauron?

Wouldn't he technically be ageless since he's a maiar (spelling?) or does this only account for his physical body's age?

Mr. Frodo

Sam always did show a sort of reverence for Frodo

I believe so. I'm sure someone might have more info, but I just searched and found that people usually give estimates for both Gandalf and Legolas.

That's probably just his length of time on Middle Earth, possibly in a mortal(?) body, given that he has technically existed since before the world, itself, having had a hand in creating it.

And Aragorn and King Theoden were roughly the same age. It's mentioned in the appendices that when they were both youths getting some combat experience, they fought together under King Thengel as allies of Gondor in some of the many battles they had against Mordor. Theoden didn't recognize him because he traveled under a fake name back then, and it wouldn't have occured to Theoden that this random dude (as far he knew) that looked half his age could possibly be his old battle comrade.

Yep, hobbit's hit adolescence around 30 and young adulthood by late 40's I believe
