Wagons are believed to have been first created in western Asia around 3500 BC. Initially, because the wheels were disc-shaped, they were pulled by cattle due to their heaviness. However, after the invention of spoke wheels, horses could pull the wagons because they were lighter. Naturally, there was a big difference between the speed of a wagon pulled by cattle and one pulled by a horse. This led to a decrease in travel time. A minor adjustment to the spoke design sparked a significant change in human civilization. Nearly all innovations start small, but even the tiniest change can have enormous consequences. Many unseen factors contribute to this innovation in our lives. - 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”
