just thought about this theory about sage energy.since pa says it increases all ur atributes why not lifespan as well. look at ma and pa they look like they haven't aged much since jiraiya was a boy. we still have to see though if it can work on humans allthough it might be able to repair the damage to naruto if he uses the kyubbi again to keep his life span normal.
what ur guys opinions on this?
I can not explain why, but I think no, it can not. Jiraya has mastered the sage mode probably at his 30's, and he still looked as a 50 years old before his death. Or do you mean jsut prolonging your lifespan without looking younger?
As we have already seen from the manga, there are ways to prolong your life, but most of these ways are in fact creepy.
Kakuzu - prolonged his life y stealing other peoples hearts and probably organs. But he looked unhuman, he was made out of black stuff and was really ugly.
Sasori - made a puppet out of himself, almost completed his immortality. But that's a creepy way too, don't you think?
Orochimaru - well, this is evident, he was stealing other people's bodies and using them for himself. To do it, he fully mastered his snake skills, a technique which was called REBORN.
Madara - is the only one who is known to have prolonged his life without turning into something creepy and conducting any experiments on himself.
Yes, he still looks human and got some awesome jutsu. maybe he has exchanged bodies with Obito, however i doubt about it, he has 2 eyes.
Most probably it is Eternal mangekyo Sharingan which helps him to live that long. We just havent speculated the full power of EMS.
Peins bodies - this is not what can be a life, is it?
it wouldnt prolong his life, at least not in a significant way
