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”
Certificates are often more valuable in proving "there is none" than in proving "there is one." For example, a birth certificate is more beneficial in proving the only person in the world by proving an unborn existence like him or her than in proving the person's existence. That is, proof of absence is more valuable than proof of existence. We don't know where value comes from. What is the real element of our existence and our occupation? - Joseph's "just my thoughts"
