I wonder if it was possible just by getting away from their planet like Kes did and the other Ocampa did was enough to start prolonging their lives. I always assumed that the Caretaker might have been putting something in their food and water. Maybe it would take several generations to prolong their life spans quite a bit.
Or it could have been something more technological in nature. For anyone who had watched Stargate SG1, remember that one planet they found where the people only lived 100 days. A child born one day was a toddler the next. It was some kind Goa'uld signal that when shut off would no longer affect them.
