Israeli Kindergarten. Dual-income couples often arrived late to pick up their children. As a result, the kindergarten implemented a rule that parents would face a fine if they were late; however, even though this introduced a penalty system, it also led to more delays in pickup times. By replacing feelings of guilt with money, paying a fee for being late became the new norm. After recognizing the mistake and removing the fine system, what happened? More parents started arriving late. When money becomes involved, the exchange of value fundamentally changes the nature of the relationship. And once that change occurs, it doesn’t revert. - 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”
