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”
Architecture has developed in response to the epidemic. The city was designed to mitigate the risk of outbreaks. However, its high population density renders it susceptible to epidemics. A potential solution to this issue involves the construction of a water supply and sewage system, which safeguards individuals from waterborne infectious diseases (e.g., cholera) by effectively separating and burying water and sewage underground. Nonetheless, the advent of vaccines has facilitated the existence of megacities with populations exceeding 10 million people. Indeed, microorganisms predominantly populate the Earth. - Joseph’s “just my thoughts”
