This has been bothering me ever since the first time someone mentioned it in a thread about plot holes.
Why?
Is it because the people like challenges a la Goku? If so, doesn't that mean everyone in the universe is just a supreme d1ckhead?
And if nobody has thought of it, doesn't it mean everyone's just stupid?

One thing I never understood is how would the dragon have enough power to make someone immortal? Surely if he was able to do something like that, he could defeat any villain if asked to do so.
