My opinion

---

There may be common utterances of super-fertile forebears to their sub-fertile descendants that they never got rattled by the numerous progeny they had raised during their constricted and constrained lifetimes in comparison to the short-fused rearing behaviors among their descendants in the face of much smaller numbers of progeny sired over much longer periods of well-endowed lifetimes. The descendants may retort that times have changed and with them, expectations and needs have changed too. On rebuttal, the forebears may explain that the core needs have not changed and may never change unless and until self-replicating life forms evolve to be replaced by self-replicating non-living things. The questions are these:

 

• If impotence, infertility and sterility could not allow firing to sire with or without desire, is this absence of sired progeny misfiring the fire within into spiraling down the ghost called mind within into inexplicable depression and related patho-physio-psychological phenomena because of the machine called body turning out to be a failure as a vehicle by driving its selfish genes into dead ends [1-8]?
• Are these patho-physio-psychological phenomena getting trapped in vicious cycles with positive feedback worsening impotence, infertility and sterility and thereafter providing fertile grounds for worsening of those patho-physio-psychological phenomena [9-10]?
• Are depressed fertility and fertile depression causing maladaptive responses to evolutionary stress with worsening incidence of precocious puberty to counter worsening incidence of premature menopause/andropause which are trying to balance abundance of populations by downsizing reproductive ages [11]?
• From perspective of climate emergency, do voluntary celibacy and childfree status still induce patho-physio-psychological phenomena as related to impotence, infertility and sterility [12]? If not so, does the control on future unborn generations or their absence per se overcome the instinctive ghost called mind being manipulated by selfish genes within the impotent, infertile and sterile machine called body just like pathogens as well as cultures inducing infertility-sterility among humans while counterintuitively gearing up overactive sexual behaviors among humans to haplessly counteract induced infertility-sterility while inadvertently spreading self-perpetuating selfish pathogens as well as cultures [13-14]?
• Concurrently, what societal percentage of lifelong non-replication by choice or by biology or by orientation can sustain a societal population growth in the most balanced format to survive and outlive the trying times of abundant populations, imminent climate emergency and maladaptive evolutionary stress on self-replicating selfish genes driving the ghost called mind crazy within the machine called body [12]?
• Is delayed fertility in combination with depressed fertility leading to progeny being born into delayed, depressed and decayed parenthood with no sibling community to mitigate and overcome parental depression and related patho-physio-psychological phenomena secondary to maladaptive and overbearing parenthood helplessly and haplessly attempting to negate the consequences of delayed, depressed and decayed fertility [15-21] for metaphorically “Saving Private Ryan” [22] considering that individual humans’ procreation is at so low level that few-numbered and far-spaced human adolescents are going through their “Wildhood” [23] under too protected conditions thus preventing them to evolve and “Behave” [24] on their own?
• Considering that modern humans get disengaged when education, taxation, and innovation among many other mandates have been implemented mandatorily by modern societies for their covert and overt selfish reasons [25-27], could it have been that ancient humans might have got similarly rattled when replication, competition, selection and evolution among other mandatory virtues were existentially mandated by nature unless some of our forebears had voluntarily decided to let go these mandatory mandates to become extinct thus allowing our other extant forebears to move on and remain existent in contrast to our some decisive forebears and their selfish genes becoming extinct by choice?   

 

Summarily, despite sexualizing sexualized sexuality as-cause-as-well-as-effect, the evolutionarily depressing an already depressed fertility may be very much fertile for evolution of fertilized depression among overabundant human populations which may be becoming existentially confused regarding “To Be, Or Not To Be” unless it turns out to be a mandatory mandate.
