Jacob's Touch

In Dr. Linus, we learned from Richard that Jacob's touch brought about changes, changes that can be seen as either blessings or curses. We know that Jacob's touch made Richard never die (at least, by his own hand) and never age. It also appeared to me that Jacob's touch revived John Locke after his father pushed him out of a window eight floors above ground. We don't know if Locke would have aged, but we do know he could be killed - just ask Ben.

So, what are the rules of this touch? Are there rules? Clearly, some who are touched by Jacob can age, or else Kate and James Ford would be the oldest children ever. Actually, I can hear some of you say that Kate is a child, but you know what I mean. We know that those who have been touched by Jacob can be "claimed" or "infected", as we saw with Sayid.

Can Sayid, Jin, Sun, Jack, and Hurley age? Is it possible that they will never die? Or can they never die until Jacob or the Island is done with them?

Is it Jacob's touch that makes a Candidate? notLocke seems to think so. If so, then Kate is surely a Candidate, as are both Kwons. Is it the touch that makes the Candidate worthy? Or is it just an acknowledgment of their worthiness? Or perhaps the touch is just to make the Candidate safe?

And what about Ben? I don't remember this, but apparently, Jacob actually touched Ben as Ben stabbed him to death. Did this touch pass on to Ben any of the qualities we're looking at? Could it have possibly turned him into a Candidate? Wouldn't that be funny?

We have to adjust to the fact that not all questions will be answered, but I sincerely hope that we get answers to some of these questions. It might help explain why these people were brought together to the Island.
