Exactly - it's a sort of catch-22 scenario.

However, if like teh Knight you have sworn to protect the grail, devoting your life to the task, then eternal life within the room that houses the grail would come in quite useful. Beyond that though, no point. Perhaps the only reason the grail grants eternal life to someone who drinks from it is as a sort of defense mechanism to ensure that the person chosen to defend it is always around to do so. Of course, if the power of the grail is useless beyond a certain point, then I guess there is no real need to defend it in the first place....Even if the Nazis did get hold of it, beyond the seal it's nothing more than a cup.

Anyway, if Indy's eternal life ceased to be once he passed the seal, what about Henry's wound| Shouldn't it have reopened causing him to die?
