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”

History professor Yuval Noah Harari said, "The most distinguishing feature between humans and other animals is the ability to believe not exist imagination." If you eat a banana exchanged with a bill from the chimpanzee, then the chimpanzee must be angry with you. The bill is just a thing to believe non-existent imagination each other in the human world, it's never important and meaningful for the chimpanzee. Unless the belief is to exchange the value, the money is just paper. This belief makes our social community. - Joseph's "just my thoughts"
