That honor goes to finding out, back duringmy first stayin China in the mid-1980s, when glasses were in short supply, that spectacles were distributed with preference given to those who had attained a high level of education, the notion being that academics and teachers needed to read for a living.
Hindsight and improved medical science has shown that duringmy short stayin Kabul, I contracted Borrelia bacteria (strains of which in the US cause "Lyme Disease") from ticks, which fell off mice that scampered over my feet during sleep, attracted probably by the bits of sweets given to me lovingly by Madaar (Mother), which I kept inmy suitcase under the bed.
