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”
Umbilicaria esculenta is a kind of mushroom. To pick this mushroom up, a picker must climb a high mountain and approach a dangerous cliff because this mushroom is growing up between rocks. Therefore, umbilicaria esculenta is more expensive than other kinds. One day, the TV show "Korean's Dinner Table" on KBS 1TV showed an episode about the mushroom picker and his old mother. "Don't sell this mushroom at a high price." said the mother, because this would be sold at a higher price, many pickers would die from over-picking even dangerous situations. We should deeply consider what is the mission of our businesses. - Joseph’s “just my thoughts”
