Nice article, I had some thoughts on that topic before but I found it interesting that it is much rarer than I previously thought it was. Most of the stories of this nature that I hear about suggest that it is the dead spirit that caused the person to grow sick and die, it is nice to hear that the living person has a choice in the matter rather than none at all.
