To enhance the credibility of your simulation, familiarize yourself with common health-related vocabulary. Use terms such as "headache," "body ache," "fatigue," and "nausea" to describe your symptoms. However, avoid being too specific, as this can lead to inconsistencies in your story.

Consistency is key when attempting to convince others of your feigned illness. Ensure that your symptoms align with one another and avoid contradictions that may raise suspicion. If you claim to have a fever, avoid behaviors inconsistent with someone experiencing an elevated body temperature, such as drinking hot beverages.
