Arwen's Fate as a mortal

[Beor]

is to die, but my question/discussion point, is, "What exactly happened to Arwen?"

I know she eventually laid down somewhere in Lothlorien and died, and they named a mound after her (which seems to happen alot), but (and this is where the movie has me all fu....messed up) did she age normally? I read it last night, and I couldnt really make out whether she aged, or if she was in sort of limbo between Eldar and Edain.

Also, when ol' Tolkien writes that she could not leave this world tilll all that she had gained was taken, did that mean that dad would have to sail and Aragorn Elessar Estel son of Arathorn would have to die, or is there more there?

Discuss.......now!!
