A study by some peeping toms reports that women are "better" at washing their hands after using the bathroom than men.
This reminds me of the old adage, "They taught me not to pee on my hands in the Boy Scouts."
They claim that this makes women cleaner than men. I am not sure this is an accurate statement. Primarily because of anatomical differences between men and women. Lets face it of the two types of urinary appendages the male is "cleaner" because it is an exterior appendage and is not apart of the mucosal membrane and negates the need to come into contact with the area of evacuation of bodily fluids. I think it would be interesting to see a study that examines the bacterial concentration on men's and women's hands pre- and post- urination visit. That would be a better measure than watching people wash their hands in the bathroom.
