Fear oldeath:

Research shows thai while the elderly often think about death, they fear dealh less than do other age groups. Thinking or talking about death is not the same as fearing or dreading it. Thoughts or conversations about death are naturally more common in the elderly, since they more likely have peers and relatives who have died or are dying. Dread of death is uncommon in persons who are not dying or experiencing some major loss, although reports show a normal and common dread of death in middle-aged persons, who may suddenly perceive how little time is left. At this stage, people find themselves confronting an existential awareness of their own mortality; with further aging, they adapt to this realization.
A terminal illness, an underlying depression, or other emotional conflict—not the awareness Of aging itself—predisposes certain elderly persons lo death anxiety. In these cases, confronting mortality is different; a terminal illness brings an awareness of dying that can lead to despondency. Eventually, most people come to terms with their fate and can reasonably accept their condition. Depression at any age clouds a person’s thinking and often increases thoughts about death. A noticeable and persistent uneasiness about death may signal underlying depression that could benefit from trealment. Evaluation is all the more important given the high rate of suicide in the elderly and the role of depression as a major risk factor.
