Free Effect. A new ice cream company in India has set up free ice cream vending machines on the streets to promote its brand. Result? People lined up at a very long distance in front of the vending machine. It was raining then, and the people in line went to a convenience store to buy umbrellas, then lined up again. Umbrellas cost much more than ice cream. However, people kept lining up. Cheap and free are two completely different concepts. When the price is low, sales increase slightly, but when it is free, an extraordinary dimension of the problem arises. It’s a privilege, so consumers are willing to pay a higher price to get something for free. Free is not a matter of reason; it is a matter of emotion. - 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”
