I've been rewatching all the Indy movies (minus the recent one, which I have no interest in) and was wondering why Indy and his dad aren't immortal or have extended life spans. They both drank from the grail, but theories online are that once the grail passed the seal, the "deal" was negated. The other theory is that you have to drink from it regularly to either have a long life (Grail Knight). The only other thing I thought about was that maybe it only extends your natural life and disease/illness aren't included in that. I don't think it's explained how Henry Jones Sr. died, but it could have been something like cancer. Any ideas?
Also I would think he would have let Brody and Sallah drink right after!
