Influence of Time: Time has the power to change the values of this world and people’s minds. The passage of time—past, present, and future—is only significant to humans, and if there is an all-powerful God, it likely holds no meaning for Him. Time accomplishes many things, and God rules the world through it. As time progresses, people change, and the world changes as well. When time flows, the world transforms, and it is natural for humans to adapt to these changes. My attitude toward time influences my values, which in turn shape my actions and perspectives. My values do not influence time; rather, time influences me. Observation is not just seeing the world but also seeing myself. It is a wise attitude to judge both myself, who is affected by changing times, and the world, which is already in flux. - 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...

The human tongue identifies five distinct tastes. With the exception of sourness, the other tastes alert us to vital nutrients necessary for human survival. So, what is the importance of acidity? The sensation of sourness arises from the concentration of hydrogen ions (H+) present in water. As the concentration of hydrogen ions rises, the pH level lowers, leading to increased acidity and a stronger sour flavor. Sourness is both the most appreciated and least favored taste among humans. We utilize the scent of decay along with the sour flavor to differentiate between edible and inedible food. When ripening occurs appropriately, it is termed “fermentation,” while excessive ripening is referred to as “rotting.” Fermentation indicates that food is safe to eat, whereas rotting signifies that it should be discarded. In essence, acidity is fundamentally tied to human survival. - Joseph’s “just my thoughts”
