Is there a way for a human character to increase their life span by any significant amount?
I want to expand his lifespan because I want him to eventually raise a dragon, but I know that's way outside of a human's or even elf's lifetime. Fluff-wise, the human is also draconic, as in he has dragon blood, though I'm not planning yet on taking any bloodline stuff for this.
We're playing Pathfinder, though D&D 3.5e material is allowed. Preferably he should remain himself and human. (This includes not becoming an evil lich.)
Also, since this will change answers by A LOT. I am going to be the host of the group. Which means I have GM duty since I'm the only one of us who's read dnd/pathfinder books.
