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”
The human tongue identifies five distinct tastes. With the exception of sourness, the other tastes alert us to vital nutrients necessary for human survival. So, what is the importance of acidity? The sensation of sourness arises from the concentration of hydrogen ions (H+) present in water. As the concentration of hydrogen ions rises, the pH level lowers, leading to increased acidity and a stronger sour flavor. Sourness is both the most appreciated and least favored taste among humans. We utilize the scent of decay along with the sour flavor to differentiate between edible and inedible food. When ripening occurs appropriately, it is termed “fermentation,” while excessive ripening is referred to as “rotting.” Fermentation indicates that food is safe to eat, whereas rotting signifies that it should be discarded. In essence, acidity is fundamentally tied to human survival. - Joseph’s “just my thoughts”
