give me a con about being Obsessed with immortality

One con of being obsessed with immortality is that it can lead to a fear of death and an inability to fully appreciate and live in the present moment. This obsession can also lead to unhealthy behaviors and decisions as individuals may go to extreme lengths in pursuit of eternal life, potentially causing harm to themselves and others. Additionally, constantly worrying about achieving immortality can prevent individuals from fully embracing the natural cycle of life and can lead to feelings of anxiety and stress.
