Answer:Aging is a natural, progressive process leading to a decline in biological functions and increased vulnerability to disease, while the stages of death and dying, as described by Elisabeth Kübler-Ross, include denial, anger, bargaining, depression, and acceptance. The initial stage involves disbelief and denial of the impending death, often accompanied by a reluctance to accept the diagnosis or prognosis. As the reality of death becomes clearer, individuals may experience anger, frustration, and resentment towards themselves, others, or even the medical system. In bargaining, individuals may attempt to negotiate with a higher power or fate to postpone or avoid death, often making promises or requests in exchange for time. As the end of life approaches, individuals may experience profound sadness, grief, and a sense of loss, leading to withdrawal and despair. The final stage involves a sense of peace and acceptance of the inevitable, allowing individuals to focus on making the most of their remaining time and finding meaning in their lives.
