What activity was George Richardson engaged in prior to the EMS call?

The context of the scenario likely indicates that George Richardson was engaged in walking right before the EMS call. Walking is often associated with active movement and can lead to various situations requiring medical assistance, such as falls or collapses due to exhaustion or health issues.

Being engaged in walking also suggests a level of physical activity that can be linked to potential emergencies, particularly if the individual experiences a sudden onset of a medical condition while in motion. Furthermore, the choice of walking aligns with common situations encountered in EMS scenarios, where individuals may have been engaging in light exercise when an incident occurs.

In contrast, skiing, working, or resting would imply different degrees of physical exertion or circumstances that may not align with typical emergencies requiring EMS intervention. For example, while skiing involves physical activity, it often occurs in a specific setting and may not be as relatable for a sudden medical event as walking could be in a standard urban or suburban context.
