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”
Vaccines have allowed people to travel worldwide. Migration and population density are benefits of vaccines. When vaccines failed to curb the epidemic, the “space” ultimately addressed the epidemic. This history is why maintaining “social distance” is essential. Hunting requires one million square meters to secure a person’s livelihood, but urbanization restricts many individuals from accessing such vast spaces. On the other hand, if agriculture can address livelihood needs with just 500 square meters, and its efficiency can increase by 2,000 times, then the perspective on the epidemic reveals insights about civilization. - Joseph’s “just my thoughts”
