One of the reasons stories are memorable is that they can create an emotion within us which then kicks of a wave of body chemicals coursing through our veins. These chemicals ensure we remember the situations that created them. We remember what we feel.

I was reminded of this phenomena re-watching this remarkable documentary called A Class Divided. The participants in the experiment are unlikely to ever forget their experience with their teacher, Mrs Jane Eliot.
