Is there really a way to die happy. If I had the motivation, I’d Google a few stories of people who had come very close to death and survived it, still remembering there last moments of consciousness. Maybe later. They would be able to tell us about their level of happiness when faced with death.
From my naiive perspective, I think the person who’s been in long term suffering, emotionally and/or physically, would be thoroughly relieved when staring death in the face. I imagine death would be a welcome relief in this case.
What seems odd though is when people say they would be happy to die doing one of their high risk activities. For instance, crashing a motorcycle/car, bungee jumping, face climbing, skydiving, I am just here to say that this is not a happy face:
