The reason the human brain is more complex and sophisticated than that of other primates is to facilitate the establishment of social relationships. The brain develops through the senses, and humans must experience them to sense. Without experience, the human brain cannot perceive. All social experiences contribute to the development of a social brain. The broader the relationships, the more socialized the human brain becomes. Through experience, the human brain can compare and organize information to communicate effectively with other brains. To empathize, we mirror the brains of others. Who we are with is also neurologically essential. - Joseph’s “just my thoughts”
The "normal human body temperature = 37°C" standard was established in 1851 by the German medical doctor "Carl Reinhold August Wunderlich", who took millions of temperature readings from about 25,000 people and reported "36.2°C to 37.5°C". However, surveys in the United States in 1992 and the United Kingdom in 2017 found 36.8°C and 36.6°C, respectively. So in the past people deemed that the discrepancy was due to errors in old measuring equipment or methods. But Julie Parsonnet and her colleagues at Stanford University's School of Infectious Disease Epidemiology found a common thread in the temperature databases: People are cooler now than they were then. It wasn't just a measurement error. They speculated that medical advances had reduced inflammation and lowered the average temperature. We don't question the obvious. - Joseph’s “just my thoughts”
