A Tiny Crevice. In other words, it is also called an affordance, permissiveness, or tolerance. A 5mm hole and a 5mm rod don’t fit perfectly together. If you hit it with a hammer, the rod might go into the hole, but only by forcing it. If they are the same size, they don’t really fit. There needs to be a slight gap to ensure a proper fit, which is known as ‘engineering tolerance.’ In this world, 5mm exists only as a concept and doesn’t truly confirm its existence. For some, ‘tolerance’ might be seen as a mistake or imperfection, but for others, it’s a principle of life that drives the world and should be natural. - 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”
