You are what you eat, so the old adage goes. And you are what you think, obviously.

This is quite true for me. In the nearly 10 years that I have been directing examinations for a national university, thereby interacting daily with various aspects of student matriculation and assessment, I sometimes have dreamed falling asleep in the exam room only to wake up sweat-drenched as the invigilator demands for the answer booklet.

Or I forgot to carry the pen to the venue; or the battery of my scientific calculator suddenly dies as the envelopes containing question papers are being ripped open. For some reason, these obviously Freudian experiences make me genuinely edgy.
