Who wants to live forever anyway right? There are better places to go to. ;-)
That's the bottomline.
Been entertaining such thoughts myself. Such as, "Why should I live longer than anybody else. Am I worthy of prevailing? To be one of the few that is worthy to receive more life energy than anybody else?
The answer always comes back: 'Existence will ultimately decide who will be needed to aid in the rebuilding of a better humanity. No matter how 'I' try to finagle my own survival, in the end, it will be out of my hands, because existence may have a different notion about this.'
It will always boil down to that famous quote: "Let thy will be done - not mine."
