Olfactory: Charles Spence, the world-renowned scientist who invented gastrophysics, explains that although aging diminishes all human senses, most people believe they would miss sight the most. However, according to quality-of-life indicators and suicide rate data, losing the sense of smell is actually more harmful than losing sight. Even if we lose sight as we age, we can still find comfort in hearing the voices of loved ones and recalling memories. In contrast, when we lose our sense of smell, there is no way to recreate those experiences, and memories of scents cannot be imagined or recalled in abundance. To enrich our lives, we should focus on increasing our scent experiences, as the ability to smell is a key contributor to happiness. - Joseph’s “just my thoughts”
Even though a country's total population is decreasing, the economic situation could be improved by increasing the total economic activity of the remaining population after the decrease. Of course, there is a statistical population threshold below which this effect occurs. Nevertheless, this effect would not work in the case of a force majeure, such as a natural disaster or the outbreak of war, however, this assumption would be valid because a rapid population decline is a highly exceptional event that would not normally occur. Therefore, an increase in the economic activity of this population should be required during an economic recession. Applying this perspective, for building a solid relationship with your followers on Instagram, the number of followers is less important than the activity between them and you. This is called the "Engagement Rate (ER)". - Joseph’s “just my thoughts”
