I loved this story. I seem to "know" when folks are going to die too. It might be because as a nurse we learn the "signs" but I would talk to the patients I had when I worked in a nursing home and tell them how much I enjoyed knowing them and if I never saw them again I appreciated their freindship and would miss them and never forget them. I would go away for the weekend and come back Monday to find that they had passed on just as I suspected they would.
I have also read stories about dogs who could sniff out cancer.
