Or, as I mentioned in another post...if Roger Linus and Ben Linus were brothers, and both Dharma Work Men, then Ben could be an awful lot older than he appears. What if your age suddenly catches up with you after a length of time on the Island? (or, if time is running at different speed on the Island, when you leave it suddenly catches up with you, hence why no one tends to leave).

All I'm getting at is that maybe Ben is really, really old in actual fact.

Frank: It's the same old story. Boy finds girl, boy loses girl, girl finds boy, boy forgets girl, boy remembers girl, girls dies in a tragic blimp accident over the Orange Bowl on New Year's Day.

Jane: Goodyear?

Frank: No, the worst.
