As a child, my mother always told me that boys were made of "Snakes and snails and puppy dog tails" whereas girls were made of "Sugar and spice and everything nice."
The clear implication of that early training was that boys are dirtier than girls.
Girls readily buy into this and regularly call boys dirty.
Science has shot that notion all to hell in this study.
Apparently, women are the nastier of the two sexes if bacteria are the criteria used to judge nasty-ness.
Well, at least now I can begin the healing process.
