god, I don’t know if there really IS a comparison to be made to human ages here, Nonnie. There is effectively no end to an Elf’s life, if they are not killed or do not become weary of living, and so there’s no real thing as a human equivalent of 30′s, 40′s, middle-aged, old-age, etc.
That said, we do know from Tolkien that most Elves are married at around 100 years of age. So that’s why that line is there.
We also know that some Elves are OOOOLD. But doesn’t mean that they are frail or their life is drawing to a close, like it would for a human? Their bodies simply do not age. So yeah.
As Elves go, Legolas is young-ish. Arwen is older than him. But Tauriel was meant to be only 600? But she’s an Elf that is 600, not a ‘twenty-something’ human, nnngh.
I don’t want to make you feel like I’m totally negative towards the idea, or that I’m being a snob about it. I’m glad you asked me, Nonnie, even though I feel like am not explaining this well! But I find it really hard to think of Elves and immortality and all that jazz being at all similar to the assumptions we make of mortal age brackets.
IDK, I can’t see Legolas (or any Elf, for that matter) having an equivalence to a human age, considering their agelessness. To me there’s just Elves, and older Elves and younger Elves… and the difference is: Young Elves aren’t as tired – or as wise. Older Elves CAN GROW BEARDS (hey Cirdan!) and get weary of unchanging life.
Other people who know Elves better than me might have some notions to put here, and I’d be glad to hear em! But that’s my little understanding of it, Nonnie, I’m sorry if it isn’t helpful *sheepish sort of look, pushes the cookies over*
