Age & WoW

[WeeBaby]

So my son and I were talking earlier tonight and the subject came up on how long I would play this game. He figures that I might get to old to play. I am only 39 and of course to a teenager, that is ancient. So the question is this. What age is the oldest person you are aware of that is still actively playing? Do you all plan to play as long as you can or is there a point where you are "Too old" to play MMO's?
