In <What Is Life?>, written by Lynn Margulis and Dorion Sagan, there is an expression, “Independence is a political term, not a scientific term.” Independence is the state in which a person can live alone without help or influence from others, using their own strength and ability. The condition of being physically separated from the community is called “isolation.” Independence and isolation are different. Isolation should not be mistaken for independence. To exclude influence and secure autonomy is independence, while deliberately cutting off relationships is isolation. Independence is based on achievement; isolation is based on hurt. To grow, you must be independent, not isolated. - 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”
