I used to believe when young that the world was a rational place, to the extent that one would live an exact number of years and die on one's birthday. Childhood fears included the witch under the bed who would grab my ankle if I put a leg out of bed, and a fear that I would fall into the toilet, shrinking and disappearing around the u-bend as I fell.
