I still feel huge frustration with doctors focusing on mind over physical health in many cases. They regularly make the incorrect assumption that the mind is causing the illness rather than the other way around. It's a convenient excuse to treat the symptoms rather than the actual cause and avoid having to say they don't know. In fact they're so over confident in their assumptions that they don't even consider the possibility they're wrong. That is the definition of ignorance and it'a a disservice to many. Myself included. It's also a diversion on the road to finding correct answers to medical issues therefore hindering medical science overall.
From what I can tell, the title of this thread (and I mean no offence by this!) is a little incorrect. The people in the study are convinced of their impending death so aren't wishing for it so much as fearful but certain of it. I guess there's an element of acceptance involved too. However, maybe I'm picking hairs. It's a good share and I'm glad you shared the article OP. Just pointing out my observation. :)
