Any empirical measurement of the contents of my mind would surely reveal that 2 percent of my brain cells still occupied by the various forms of symmetry hammered into them during a sweat-inducing semester in crystallography , 3 percent are holding out for the day when I will again need to diagram the complete Krebs Cycle, and at least twice that number are cheerily engaged in storing the Latin names for North American freshwater fishes. But these are minor players in the brain game when they’re stacked against the three largest mental regions: theme music to 1960s and 70s sitcoms, obscure actresses, and, of course, B movie quotes. In 2008, I was lucky enough to attend the Democratic National Convention.
