From what I've noticed all of practitioners who have been shown to have a long life span and faster/better healing compared to mortals have been skilled magic users. So what about the practitioners with low to moderate skill? Do they have these abilities as well? And what about the specific examples like the street wolves? Will they live to be hundreds of years old if they aren't killed? Or people like Charity who were born with the magical talent but stopped using it? Will she outlive her children and husband if she isn't killed? (Except for Molly) What exactly causes a practitioner to be granted the abilities of a longer life span and better healing?.... Thoughts?
Anybody who uses magic much gets
some benefit (unless something about the magic itself messes them up, which is probably possible with the nasty forms). But the minor talents and minor practitioners get minor benefits. The stronger you are, and the more you study it and use it and refine it, the better the side effects.
So a minor practitioner might lives a little longer, and age a little slower, and heal a little better, but probably nothing too noticeable, it might easily just be mistaken for good genes.
That sort of thing. As the power levels rise so do the benefits, until you get to Council level and potential life spans of 400 years.
