All the way from Arena to Oblivion I've played the same character, a Dunmer male. However, Arena and Oblivion are only 50 or so years apart, so if I was a young Dunmer in Arena, then it is possible that I would still be alive in the time of Skyrim. I'll be pretty whithered and grey, but I was planning on playing as an old Dunmer hermit anyway.
So to all you out there who played as elves in previous games, would you want to reprise that character as an elderly version, having to relearn all those skills you've since forgotten in order to fight one last battle?
EDIT: After some interesting points, I added another question.
