This paper analyzes the pursuit of life extension through emerging scientific technologies in modern secular society alongside the theological understanding of immortality, arguing that cultivating the Ars moriendi, or the art of dying, can mitigate the motivation to pursue life extension technologies. To this end, it first delineates how transhumanist strategies, including biomedical gerontology, neural interfaces, and mind uploading, fall short of genuine immortality due to their material and personal identity issues. These solutions effectively provide forms of life extension rather than true immortality. Second, this paper highlights how the underlying fear of death fundamentally drives the pursuit of these technological pathways. However, fear-based life extension does not guarantee a contented or meaningful quality of life despite an extended lifespan. Third, drawing on the medieval Ars moriendi tradition, the paper posits that alleviating the fear of death through death meditation can foster acceptance of mortality and a more profound sense of living well. In conclusion, this paper contends that shifting from fear to hope may diminish the desire for life-extension technologies by demonstrating how contemplating death reorients the discourse from mere survival to the art of living well; the art of dying well is inherently connected to the art of living well.
