Architectural engineers are people who create buildings. They design, construct, and build these structures. It is important for architectural engineers to be skilled in their field, as they need their buildings to survive strong winds, hurricanes, eaartquakes, and tornados, depending on which area in the world they are building in. If they don't apply the science of construction, the building could collapse upon itself, and severly hurt people.
A reason being in architectural engineer is enjoyable is because you can create incredibly cool structures. For example, you could be assigned to create a football stadium, or maybe a skyscraper. However, architectural engineers need to know the science, math, and technologies behind buildings to create a safe, cool design.
