In access to insight we find this passage:
"Let us first see what happens when a worldling dies. It is an accepted fact that everybody fears death. We also fear the unknown; therefore death is doubly fearful because we know least about it. It seems reasonable to assume that at the root of all fear there lurks the fear of death. In other words we fear everything which directly or indirectly threatens our life. So long as our bodies are strong enough, we can either fight or run away from the source of fear, with the intention of preserving life. But when ultimately we are on the deathbed face to face with death and our body is no longer strong enough to flee from death, it is highly unlikely that we will mentally accept death with resignation. We will struggle hard, long for and crave for life (ta.nhaa), and reach out and grasp (upaadaana) a viable base somewhere as the dying body can no longer sustain life. Once such a viable base, for instance a fertilized ovum in a mother's womb, has been grasped, the process of becoming or growth (bhava) starts there, which in due course gives rise to birth (jaati). This is what is referred to in the twelve-linked pa.ticcasamuppaada as "craving conditions grasping, grasping conditions becoming, becoming conditions birth." Thus a worldling dies and is reborn."
Now I wonder, let's say that one has lived what he/she deems to be a very full and rewarding life, without spiritual training though because it was never his or her "thing", but one is very happy and content about the life he or she has lived, and has now fully accepted the fact that time to die has come, that nothing can be done about it, therefore is resigned to die. Let's say that person even longs for death now as his/her body is now old and making life not very "enjoyable" anymore. So when death comes, let's say that person welcomes it and does not graps for life like the way it is described in this passage. Is it possible for such a person to not be reborn? I am aware that this question may seem a bit silly, a bit gullible since I am not taking into consideration the kammic aspect of rebirth here, but again, it is probably the case for a lot of people to die with this state of mind, this acceptance and even relief that death is "finally" coming. Even people who die at a younger age from grave, long-term illnesses for example, and will eventually say "I'm ready" on their deathbed, as if they were no longer afraid of death, had fully accepted it and were actually ready for it...
