It took 3,000 years from the appearance of smallpox in the world to the development of a vaccine. It took 13 years for AIDS, 5 years for Ebola, and just 4 months for COVID-19. Seven days after the COVID-19 outbreak was reported to the WHO, all of the viral DNA sequences were identified. The rapid development of an mRNA vaccine in such a short timeframe has never been achieved in human history. This demonstrates how remarkable progress in biology and biotechnology has become. Similarly, the pace of wealth creation and economic growth has also sped up. It is a recent phenomenon in the long history of human life that we now measure time in seconds. We need to understand what kind of world we are living in right now. - Joseph’s “just my thoughts”
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”
