Opportunity Cost: Making a choice means sacrificing something else at the same time because we can’t have everything. If the value of what is given up is significant, then the choice incurs a relative loss, and it is up to the CEO to recognize this as a cost. In reality, whether I am aware of the opportunity cost or not, it still impacts my current financial situation. However, to calculate profit or loss as an opportunity cost, there must be a future opportunity to forgo the current choice and select an alternative. No one should keep repeating the cycle of giving up and choosing without knowing whether the next decision will be beneficial or not. Giving up is worthwhile only when the next option is good. - Joseph’s “just my thoughts”
Architecture has developed in response to the epidemic. The city was designed to mitigate the risk of outbreaks. However, its high population density renders it susceptible to epidemics. A potential solution to this issue involves the construction of a water supply and sewage system, which safeguards individuals from waterborne infectious diseases (e.g., cholera) by effectively separating and burying water and sewage underground. Nonetheless, the advent of vaccines has facilitated the existence of megacities with populations exceeding 10 million people. Indeed, microorganisms predominantly populate the Earth. - Joseph’s “just my thoughts”
