From the Perspective of a Biologist or Medical Researcher, a Person

From the perspective of a biologist or medical researcher, a person who has been cursed or 'hexed' can die from the hex because, or only when:

A) chronic stress affects his or her blood volume and blood oxygen levels, inducing traumatic shock.
B) chronic stress leads to hyperactive breathing action, which brings on a loss of consciousness and this, coupled with self-starvation, can actually kill.
C) the hexer has actually poisoned the hexee (the hexed person) .
D) fright is so intense that the heart instantly stops beating.
E) This question is bunk: a hex cannot kill.
