Real change happens so quickly that we often don’t notice when it occurs. The changing of seasons is a good example. Clearly, winter and spring are very different. It’s hot during the day and cold at night, but when we see spring flowers blooming along the roadside, we realize spring has arrived. We tend to think that big changes will feel different, but sometimes small signs reveal the change. For instance, when our foreheads sweat even with little movement, we recognize that the temperature is getting warmer. What changes might you not notice or recognize? Perhaps your weight? - Joseph’s “just my thoughts”
A big supermarket can do business in the suburbs because of wheels. If someone asked me what is one of the greatest inventions in human history that civilization has ever developed, I would say "wheels." The automobile is also a wheel. Shopping carts are also wheels. Without wheels, how many people would go far and carry heavy loads? Mass distribution is possible because of wheels. To do bulk sales, you have to have a lot of inventory. That means you need a lot of storage space. It also means you need cheap real estate. The trivial circle, the wheel, is the key to solving all these constraints in one shot. - Joseph’s “just my thoughts”
