Everything that is expressed and recorded externally, such as cell phones, computers, memos, books, and drawings, is an extension of the brain. Our brains aren’t just inside our bodies. This concept is important because extending the ego greatly influences how we see the world. We pay close attention to topics that involve us personally. Self-relevance is a key factor that drives our lives. Personal relationships and possessions get a lot of focus, while other areas seem less important. This is due to a feature of the human brain called ‘selective cognition.’ As civilization advanced, humans delegated parts of the brain’s functions to machines. It was inevitable to make good use of these tools. We should take an interest in the Homo Faber. - Joseph’s “just my thoughts”
Human blood is a liquid that maintains a pH between 7.3 and 7.4. A change of just 0.2 in pH can be fatal. The substance responsible for regulating blood pH is carbonic acid. When carbonic acid dissolves in the blood, it creates a cooling sensation, contributing to the appeal of drinking soda. Humans convert food into glucose through digestion for energy, and this glucose combines with oxygen in a process called breathing to generate carbon dioxide, water, and ATP, which are essential for energy production. A significant amount of carbon dioxide is produced in this process. To meet a daily energy requirement of 2,560 calories, one needs to burn 640 grams of glucose with oxygen, resulting in the production of 938 grams or 552 liters of carbon dioxide. When carbon dioxide dissolves in water, it forms carbonic acid, which circulates in the bloodstream and exits the body through the lungs. While some argue that soda is unhealthy, especially for individuals with specific conditions, it is es...
