I think about death from time to time, not so that it's debilitating but perhaps something akin to mild "Depressive Realism" minus any clinical concerns

For me death has two sides, for as much as I abhor the thought of my demise, I understand it delineates my existence, given that if there was no death for me, then at some point going forward, life would lose its meaning.
That all said, I would like to choose the time and place of my death, as such I most certainly do not want to die in my sleep and miss the final experience. After all, what is life if not experience, and what is death if not the cessation of same.
I am under no delusions that there is any kind of an afterlife/rebirth/final judgment etc. I would argue that all empirical evidence points to the fact that when you die, it's the equivalent of an infinitely long, ultra-deep sleep and nothing more.
You?
