Marathon runners rarely smile before, during, or after the race and usually have a very serious expression. If there were aliens, everyone who participated in the marathon might be considered a criminal because they don’t look happy. Humans think they only enjoy happy and joyful work and avoid hard, painful work, but in reality, human motivation is more complex.

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”
