use a dictionary to help answer the question?
should you hire a wraith to be your personal trainer at the gym?
To answer this question, we need to understand what a "wraith" is. According to the dictionary:
Wraith: a ghost or specter, especially seen shortly before or after a person's death; an apparition of a person, especially one seen shortly before or after their death.
Based on this definition, it is highly unlikely and impractical to hire a wraith as a personal trainer at the gym. As wraiths are associated with being spirits or ghosts, they do not possess physical bodies to engage in physical activities like exercising or training.
