So there's that.
In another digital community i'm in, there's discussion about the formation of Death Cafes:
Our objective is 'to increase awareness of death with a view to helping people make the most of their (finite) lives'.
A Death Cafe is a group directed discussion of death with no agenda, objectives or themes. It is a discussion group rather than a grief support or counselling session.
I'm not sure i feel a taboo around talking about death. I certainly feel a taboo around talking about suicide in the sense that i suspect a listener will be more on alert for "cries for help" than actually listening. It's the choice of continued existence or not, though, that has driven my awareness of death.
