Being exposed to something your allergic to can potentially cause you to be sick. Being sick is your body's way of slowing down your cognitive functions, so that it can focus on getting rid of the thing that is making you sick.

Example: If you are allergic to peanuts, and you eat one, there is a high chance that you will be sick.
