To add to some of the comments on the first page (I haven't read all 6 lol), I agree that although not many of us are suicidal, we are 'terminally orientated'. I just think it comes from being so relaxed and in tune with ourselves, and we know and accept the risks that we take, and that death is always minutes, sometimes seconds, away.
Even me, I'm pretty at peace with myself. I am not suicidal, never really have been, but I am not afraid of death. I try and be safe when diving, I'm not trying to get myself killed, but I'm not particular afraid of a SWB... I think I'd just kind of laugh it off if I died.. be like 'haha.. I should have known better'.
I think it's just that we are just put in a very curious situation.. being haunted by death, and yet being very relaxed. I think that changes our general outlook toward death.
I don't want to die, but.. if someone told me I have a few minutes left to live.. I'd be pretty relaxed.
But being okay with dying and not afraid of it, and actively wanting to die, are not the same thing. I've heard that people who don't fear death should seek psychiatric help... that's absurd if you ask me.
