Half of us will get cancer. I firmly believe that stress and trauma are the leading causes of death, albeit seemingly indirectly. There's no way I'm coming out of what I've been through, with my mental wiring, unscathed. It's all connected and it's entirely silly to think otherwise.
With that said, because it is all connected, I think there is untapped potential to redirect the trajectory of your physical well-being, not unlike the placebo effect (and its equally valid nocebo effect). It's just that it takes a great deal of focus and open-mindedness, and of course, nothing is ever a guarantee.
If (when) I get whatever diagnosis I get (probably cancer), I will probably have to battle my depression, but then I will turn it around as best I can with these sorts of efforts. Why don't I start now? I have, but only in small ways. I think I operate "best" with a fire under my ass, probably because I'm a bit morbid and generally otherwise ineffectual without something darker/heavier, or at least a distant vision, motivating me.
I don't consciously fear death at all and have never related to people who do. I don't have any anxiety about it, but if the threat arrived, I know that I would. I don't meditate upon death, but I'd like to consciously face my mortality in a mindful manner, for spiritual reasons. I do think it's better to accept it up front as a natural, normal stage of existence, a mysterious transition.
I'm an atheist and believe not in heaven nor hell, but I feel spiritual about things from a very particular perspective that takes into account the metaphysical. Humans are quite blinded and restricted by their thirst for scientifically proven knowledge, and generally neglect to acknowledge and appreciate the beauty of repeating patterns all around us. This also gets into Alan Watts land real quick with me, and since he's already explained it better than I'll ever be able to, I'll just leave it as he's laid it out.
Mkay... great 2 am insomnia talk. I'm gonna attempt to leave this physical plane and enter the mysterious plane of dreams now.
