One of the key principles of money is ‘opportunity cost.’ It means that when I buy something, I have to give up something else in return. We think we buy because we need something, but we often forget that we could buy something else instead. We rarely consider ‘opportunity cost’ when making a purchase. We do not compare other values against our needs. Buying something means giving up something else, but we often don’t realize it. When we spend money, we should also consider the ‘opportunity cost’; yet, in reality, we aren’t trained to do so. By making a purchase, we bypass the value comparison that may not offer any additional benefits. Maybe it’s because we lack knowledge, or perhaps the idea isn’t appealing. - Joseph’s “just my thoughts”
Approximately 85% to 90% of the global population is right-handed, while the remainder is left-handed, with very few being ambidextrous. Throughout history, horses have served as a primary mode of transportation for humans. Typically, right-handed individuals mount a horse from the left side, relying on their right hand to grasp the saddle for support. If a person approaches the horse from the edge of a busy road on the left, this naturally orients the horse’s movement toward the left side of the road. Consequently, human anatomical tendencies have influenced the direction of road traffic. This practice led to the establishment of the left-hand shipping rule for vehicles, ships, planes, and even space shuttles. Thus, our civilization on Earth represents a legacy shaped by human anatomical traits. - Joseph’s “just my thoughts”
