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”
British anthropologist Robin Dunbar was certain that primate cerebral neocortical capacity determines the number of social relations. He definitively established the limit of human relationships at 100 to 230 people. The average value of 150 people is known as Dunbar's number. In the world of chimpanzees, 30 is the absolute maximum. However, fewer than 12 people in the world can sympathize with me. My best friend is now reduced to 3 or 4. The relationship quantity decreases to the square root value and increases to the square value. Three or four of my best friends will eventually connect with people from all over the world. This is the same principle as when one or two virus-infected people infect the world. Focus on your best friend. - Joseph’s “just my thoughts”
