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?

My apologies if this has been discussed before but I was curious if it has been established that a death curse has to be cast on the person who is responsible for the wizards death? The reason I ask this is because if this isn't the case then could a wizard's death be used in positive way instead of cursing someone? By this I mean instead of harming the person who is killing you you instead use the power of your death to boost the power of another magic user. Or maybe something less permanent like using your death to power or boost the effect of a spell being performed by another. We have seen rituals being powered by human sacrifice which wouldn't be much different.

I think it would be cool to see an important magic user character know they are about to die and use their death to boost or give power to a spell or ritual that Harry attempting to perform. Or give Harry another boost in power when he needs it. I love me a good willingly heroic sacrifice in stories and if this is possible I think it would make a good way for certain characters to go out with a bang....
