I read somewhere, maybe a note, maybe not, how they were granted long life enough not to sort of break their natures, because their bodies could not handle such things in excess of that they were given and also their Doom. I agree with you that they should have no share in the burden of the Doom of the Elves when they had their own Doom to embrace.
