Since air is an essential element for survival, its value is infinitely high; however, because it can be obtained anywhere, its price is effectively zero. Nevertheless, pure 100% oxygen is rare and can have a price. The distinction between value and price is important, but many people don’t understand how they differ. Exclusivity of supply is necessary to assign a price to something’s value. Exclusivity means only you can supply it, and people can only buy from you. Time also makes exclusivity. That is the message that you cannot buy it without now. Universality creates value, and scarcity creates price, thereby placing a value on that value. But these two contradict each other. Wealth is always built on contradictions. That’s why business and investment can be so challenging. - 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”
