Compared to the era of a self-sufficient barter economy, everyone’s happiness is greater in the exchange economy, where each person divides their labor into what they do best and exchanges what they produce. This is because the division of labor is more efficient than self-sufficiency in productivity and can further reduce production costs. At this point, a means of exchange agreed upon by society is required, which is called money (currency). In other words, in the exchange economy, specialists who excel in one field are more advantageous for survival than ordinary people. An all-round player is more likely to face starvation. Therefore, a generalist is only advantageous for survival when they can organically integrate their diverse abilities in a specific field or situation, while also managing and restricting the scope of their activities and conditions. - Joseph’s “just my thoughts”
Humans, among Earth’s creatures, have the largest whites in their eyes, making it easy to convey the movement of the eyes outward. For this reason, eyes communicate a great deal to others. With just a glance, it’s easy for humans to intuitively grasp a person’s emotions. Most herbivorous animals have horizontally shaped pupils, an evolutionary adaptation that allows them to detect approaching predators even while they bow down to graze. The eye serves as an emotional and social organ. - Joseph’s “just my thoughts”
