This is interesting, and I find it highly believable. I was reading a book not too long ago, can't remember which one, that described an experiment
done in a semi-remote tribe somewhere in the Pacific I believe. Certain tribe members were told that their friendly neighborhood witch-doctor had cast
a horrible spell on them, and that they would die. It wasn't true, but they believed it, and there were deaths just days after. I do not know if this
is true, how many people, etc, so it doesn't sound like a real experiment, but then again the source of that information is unknown, so I will do
I came across another similar story, equally vague, stating the same thing. So I don't know, but it ties in to what you are saying in the op.
So it seems sorrow as well as fear can kill.
