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”
Yeast consumes glucose and produces alcohol along with CO2. This action serves as a defense mechanism to protect against other microbiomes. In other words, the alcohol produced by yeast acts as a poison to eliminate other microbiomes. Thus, a solution with over 70% alcohol concentration can effectively eradicate the COVID-19 virus. We gladly consume the poison that yeast produces in liquor. Probably, isn’t there only a very thin line between happiness and unhappiness? - Joseph’s “just my thoughts”
