Immortality and the sons of Elrond

I vaguely remember reading something about that about two weeks ago.

"The Tale of Aragorn and Arwen" indicates that Arwen hasn't aged much at the time of Aragorn's death:

"She was not yet weary of her days, and thus she tasted of the bitterness of the mortality that she had taken upon her."

It appears from the text that she dies of grief and not old age, so it's not clear that Elladan and Elrohir would have died at this stage, had they chosen to become mortal. It has only been 120 years since Elrond has left.
