Not quite the sort of story I’d expected to find at Bloomberg, here I was thinking they covered matters business and financial, but it seems that changes in pubic… grooming habits (Brazilian anyone?), have resulted in a decline in populations of pubic lice:
Pubic lice are usually treated with topical insecticides, which once included toxic ones developed before and during World War 2. While they aren’t known to spread disease, itchy skin reactions and subsequent infections make pubic lice a hazardous pest. Clipping, waxing and shaving the groin destroy the optimal habitat of pubic lice.
