A common trend right now is the modernization of buildings through smart homes or buildings. With this comes a centralized control system, or smart hub, that links the various systems in a building. This control center can be compared to the human brain, which also controls and connects various systems within the body. Without this centralized control, both the body’s and building’s systems could not act cohesively.
Similarly, many houses are outfitted with security systems to keep unwanted intruders out. This can be compared to the immune system within the body, which also fights off unwanted viruses that can harm the body.
