The problem regarding acquisition of comfort.
It is unbelievable how convenient our world has become, compared to any mediaeval standards. Any mediaeval peasant could only dream of such convenience and general comfort of life. We do not have to worry about food, water, shelter, long cold winters. However in the process of that, we have lost the sense of life. There isn’t a fight for survival anymore. Hence, there isn’t anything that pushes a human for life. Our society has lost the meaning of life. In day-to-day rituals, in avoiding death in daily life, the traditions which lived for generations. Our life has become too easy. Not to forget, our bodies are made to survive the harshness and the ultimate cost for living on Terra, which has been taken away and never truly replaced. The amount of problems a mediaeval peasant had he one had to worry about, isn’t that far from what we today have. So, to compromise, our societies had to replace the problems we had to fight for everyday, once they have been largely solved. And indeed, humans have created new problems they have to deal with, in the place of surviving in the literal sense of that word. What does one have to do in this world? Is there a reason to exist for oneself? Any species have evolved for survival, including us, however when we have got rid of the need to survive, what is the purpose for existence? I am sure, that the primary cause of large anxiety and other mental health issues come from the lack of survival. Zoochosis is a term referred to captive animals, who because of the unnatural environment endure mental health issues, regarding the stereotypic behaviour they acquire. We are no different from the goal of existence of any other species, which is survival. Likewise, if we do not actively endure active threats to our survival, which tempers us for better ability to survive in that environment, we degradate. And in addition, when any species is put into a sterile, easy and comfortable environment, it may lead to severe mental health issues exactly regarding the lack of survival action. We are not an exception.
