Sometimes when I am thinking about large numbers, or complex numbers, or tricky geometric issues like the shape of the pieces of leather that make up a football, I have something approaching a panic attack, dizziness, nausea and acute anxiety because my mind cannot encompass the problem. I don't have this when contemplating other matters at all.
When I was a child, my most awful recurring nightmare always involved me being obliged to count the number of tiny units in a vast area, like a mosaic the size of a football pitch, for example. I would get so far and then have to start again because I lost track.
Actually reading this back, it doesn't seem so shameful at all. But them's the rules, folks.
