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”
The first civilizations of mankind originated in arid climates. The Mesopotamian and Egyptian civilizations are examples. A city is relatively safe from infectious diseases if it is drier than wet. The key is water. It is a river where there is water while it is dry. Therefore, the shape and location of the river are important. A dry, watery zone is formed when the river flows from north to south. In other words, the city was born under the influence of disease. - Joseph’s “just my thoughts”
