wonder why I'm coughing, I stayed indoors all day to avoid the pollution

The video effectively uses a relatable problem (pollution and its health effects) and visual evidence (smoggy cityscapes, poor air quality reading) to create a compelling and shareable piece of content.

The creator questions why they are coughing despite staying indoors to avoid pollution. The video then shows outdoor city views with smog and a car interior with an air quality monitor displaying a "Poor" reading.
