Now this would make a cool project for a science fair:

He was nominated for a Nobel Prize. I don’t care about any of this. Shafik won my heart by publishing a paper in European Urology in which he investigated the effects of polyester on sexual activity. Ahmed Shafik dressed lab rats in polyester pants.

There were seventy-five rats. They wore their pants for one year. Shafik found that over time the ones dressed in polyester or poly-cotton blend had sex significantly less often than the rats whose slacks were cotton or wool. (Shafik thinks the reason is that polyester sets up troublesome electrostatic fields in and around the genitals. Having seen an illustration of a rat wearing the pants, I would say there’s an equal possibility that it’s simply harder to get a date when you dress funny.)
