In reference to this classic:
For over half a century I have not found a definitive answer to this question, “Do you get cooties from girls, or do you get cooties from boys?”
So far, informal polling shows a 50-50 split on the answer. Usually the girls insist you get cooties from boys, while the boys insist girls are the source. Now my knowledge of microbiology is limited, but this does not sound like the typical pattern of pathogens. One sex must be the source of these undesirable parasites. Does anyone know of definitive research in this area?
