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”
Salt is a crucial ingredient we consume daily, neither from animal products nor from vegetables. The salty taste plays a major role in determining what we find delicious. When restaurant food is overly salty, customers often complain, but if it’s not salty enough, they typically remain silent and don’t revisit after their meal. Salty taste serves as a standard of flavor and is essential for life. Salt must maintain a specific concentration in our blood, known as osmolality, to support our existence. This necessity also explains why we may dislike or spit out food that is excessively salty. Essentially, our reaction to saltiness stems from an instinct for survival. Thus, it goes beyond mere pleasure; it is a critical aspect of our survival. - Joseph’s “just my thoughts”
