Volatility and Investment: The phenomenon where an asset’s price fluctuates over time is called volatility. Owning and reselling this volatile asset is known as an investment. The concept of buying and reselling an asset often causes us to overlook the fact that this process involves a trade-off between low-volatility and high-volatility assets. Cash is less volatile than stocks, and stocks are relatively more volatile. In other words, investing involves exchanging low-volatility assets for high-volatility assets and then switching back to low-volatility assets. Meanwhile, surplus profit is generated by the price differences caused by volatility. What would happen if we traded only highly volatile assets with each other? We would probably hesitate to exchange assets and might refrain from investing. In investing, there must be both low-volatility and high-volatility assets. - 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”
