Food, typically through smell wakes a characters up
In fiction for some characters at least, food is as good as if not better than smelling salts at waking someone up. For some characters it may require that the food is a favorite food. The typical cycle of this trope is a character that is faint, asleep, unconscious, perhaps even a coma smells food. The character wakes up, and then devours it. In some cases another character is deliberately trying to use the smell of the food to rouse the intended target. Also see: Follow Your Nose.
