Are you young? If you’re younger and have never faced the possibility of death, it is easy to forget about its intimate inevitability. Older adults must face their mortality everyday, they’ve had years to live life and are not invested in the delusion of human invincibility. Adults thinking and talking about death is a way to normalize it, to make it feel more manageable and relatable. Anxiety comes from uncontrollable fears. If you eliminate those fears through discussion and commonality, that anxiety reduces. It makes prefect sense that, considering your context, you experience a different perspective on death that may seem less anxiety-provoking.
