"If the extreme case of the suicide or the particularly pessimistic group is not considered by you to be a legitimate or real risk, then for the purposes of this presentation, these examples can be replaced by other cases. For example, the case of people who struggle with serious existential difficulties (like the ones commonly treated by psychoanalysts). Or the case of people with common health problems: we currently have a list of more than 7000 diseases that affect our physical and mental health, and which can drastically change the quality of our lives, even very suddenly. Not to mention, of course, the natural process of aging and fatigue to which we are all subjected. Or yet, the case of people who do not look for professional help, but in order to continue living or surviving they need to intoxicate themselves, change their state of consciousness with legal or illegal drugs, create psychosis, etc. Anyway, even for one who is not a tormented suicide, life does not seem to be so easy. Sometimes an individual needs years of therapy in order to become minimally stable. And what if the new being, our child, find themselves at some moment in such a condition? Notice then how a common decision, whose habit is considered noble, can bring an immense suffering. It is then that the true non-triviality of this decision begins to appear, as well as how important (or even necessary) it is to have a greater reflection and sensitivity in this subject. But always from the perspective of the new being, and not only from our perspective as prospective parents."
