In case you have ever questioned the value of thorough wiping and regular changes of underwear, here’s a reason. In people with poor bathroom habits or 1960s Air Force hygiene restrictions, fecal bacteria migrate. Wright-Patterson researchers sampled thirteen sites on the men’s bodies to check for E. coli. It was a remarkable Diaspora. Fecal bacteria had made its way to the men’s eyes, ears, and, in two cases, toes. Five out of six of the Soviet subjects who sat in armchairs for thirty days developed folliculitis—bacterial infection in the hair follicles on the skin. Three developed boils—especially bad, swollen, painful, infected follicles. (The Soviet paper uses the old-timey term “furuncle.” You almost want one just to be able to go around saying “furuncle.”)
