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”
The "normal human body temperature = 37°C" standard was established in 1851 by the German medical doctor "Carl Reinhold August Wunderlich", who took millions of temperature readings from about 25,000 people and reported "36.2°C to 37.5°C". However, surveys in the United States in 1992 and the United Kingdom in 2017 found 36.8°C and 36.6°C, respectively. So in the past people deemed that the discrepancy was due to errors in old measuring equipment or methods. But Julie Parsonnet and her colleagues at Stanford University's School of Infectious Disease Epidemiology found a common thread in the temperature databases: People are cooler now than they were then. It wasn't just a measurement error. They speculated that medical advances had reduced inflammation and lowered the average temperature. We don't question the obvious. - Joseph’s “just my thoughts”
