Free Effect. A new ice cream company in India has set up free ice cream vending machines on the streets to promote its brand. Result? People lined up at a very long distance in front of the vending machine. It was raining then, and the people in line went to a convenience store to buy umbrellas, then lined up again. Umbrellas cost much more than ice cream. However, people kept lining up. Cheap and free are two completely different concepts. When the price is low, sales increase slightly, but when it is free, an extraordinary dimension of the problem arises. It’s a privilege, so consumers are willing to pay a higher price to get something for free. Free is not a matter of reason; it is a matter of emotion. - 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”
