Death isn’t traumatic? My brother in law died earlier this year, and his kids were very much traumatised (not to mention the rest of the extended family).Death isn't PTSD traumatic, IMO, unless it's a gory death that happens right in front of you. It's not graphic, it's not invasive, and if it's something that's done to you then you ain't going to any comedy gigs afterwards
I think we need to separate out grief from trauma here, too. Death induces grief much more so than trauma.
The other thing is that death is a leveller, it happens around everyone, and, eventually, to everyone.
