In this respect, science has eluded the obvious; the personality profile of the suicidal person experiencing chronic pain may not synch with the hopeless, or weak, image with which most people might associate him or her. For this person, exposure to sustained pain may have weakened natural fears surrounding death, for much of this fear, in most people, is related to unknown pain and suffering. For a person coping with chronic pain, these factors are familiar, and therefore less threatening. According to Joiner, "The natural and deep fear of pain, injury and death stops people from hurting themselves, and this includes people who have high desire for suicide. It might not be as hard for someone who has already had to contend with a lot of physical pain."
