We usually think of “investment” as giving effort or money to someone. But investing is more about exchanging what you have for some value, and the object of the investment has some worth rather than just giving something away. Some exchanged values can be monetary or moral. If I swap my cash for moral and social benefits, it becomes a religious or social contribution. However, if the object of exchange is an asset with a specific monetary value or potential for profit, it is an economic investment. The world is designed to facilitate some form of value exchange. The main idea of investing is to trade low volatility for high volatility and then switch back to low volatility over time. The former is called an investment, and the latter is called an exit. Cash tends to be less volatile, while stocks and digital coins are very volatile. By exchanging assets with small volatility, stability is maintained, but wealth is not necessarily increased. - 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”
