Death across the lifespan: Age differences in death-related thoughts and anxiety.

Many studies have found age-related declines in death-related anxiety. Why do death-related thoughts and anxiety decline across the lifespan when exposure to, and likelihood of, death increase over time? In Study 1, a cross-sectional survey of 2,363 adults, death-related thoughts declined across the lifespan. In Study 2, a longitudinal study of 9,815 adults followed over a 4-year period, death anxiety declined across the lifespan. Further, greater social support predicted lower levels of death anxiety over time, after controlling for self-rated health and chronic illnesses. Close relationships serve emotion regulation functions to decrease death anxiety and thoughts across the lifespan.
