Final answer:
Religiously-spiritual adults and those completely secular may fear death less due to their beliefs. Those without a solid belief system may fear death more. Religion offers coping mechanisms like hope of an afterlife and community support.
Step-by-step explanation:
1. Religiously-spiritual adults are less afraid of death. They view death as a transition from one life to another, and most Americans believe in an afterlife.
2. Those totally secular may also fear death less, potentially due to acceptance of mortality or different philosophical understandings of life and death.
3. Those in between strong religious belief and secularism tend to be most afraid of death, possibly due to uncertainty or lack of coping mechanisms provided by a solid belief system.
4. Religion provides adults with coping mechanisms that help them deal with their own deaths, including the hope of an afterlife and social support from religious or spiritual communities.
