The science is really simple but counter intuitive, i'll give you that. Yes, nobody forced me, but I was NEVER able to NOT make this thread the current state of the Universe. The very thought that lead me to open the thread was an electro chemical reaction born from my genotype being stimulated by the external factors(which includes lack of activity). Let's say I was bored and because I talked about this subject in the past, the sum of my experience led to this moment.
Let me give you a more palpable example. Charles Whitman was a infamous mass murderer. Upon his autopsy, medics found out that he had a brain tumor pressing on his amygdala, "a part of the brain related to anxiety and fight-or-flight response". Suddenly from a piece of shit human being who killed innocents willingly, we see an unlucky dude who never asked for this brain tumor. The reason everyone can see the exact cause-effect in this case is because a tumor is something very palpable and understandable. But if you could map the ENTIRE brain counting every synapse and all his memories, we could clearly see that EVERY misdeed he commits is cause by a micro "Charles Whitman tumor". Whether it's the deranged childhood or simply bad genetics(none of which were chosen by the individual).
