The aim of the theoretical work is to increase the consciousness of death, reduce anxiety related to death issues, and study the various factors that affect the fear of death. Death is still a taboo topic and it is necessary to investigate anxiety and fear of death. Social workers should not allow the theme of death to be taboo for them. During their schooling, as well as in work with clients, they should be educated so they can talk about issues related to various losses and even death itself. Therefore, this paper deals with the fear of death in old age and the correlations of fear of death. A survey found that there is a difference in the strength of fear of death between different age groups, the relationship between fear of death and life satisfaction. Older people compared to other age groups are less affected by death, but some research suggests that fear of death is equally experienced by both younger and older people. Concerning life satisfaction, the findings from the literature point to a negative connection with fear of death. Gender differences are also compared to the fear of death and women are more likely to accept it as men have a lower rate of fear of death, but more death is avoided. Finally, the influence of religiosity on death fears so people who are intrinsically religious have a lesser sense of fear of death.
