Emotions are a mental/psychological phenomenon that occur in most humans. Emotions seem to be found more often in isolated females than isolated males, and more often in females in general. Interestingly though, males who are exposed to females on a regular basis also exhibit symptoms of having emotions. Thus, it is theorized that emotions arise from the ovaries and are transmittable through prolonged interaction with a carrier.
