A recent study from the University of Arizona has found that a woman's workspace could contain up to four times the germs than those of her male counterpart. Despite her potentially neat appearance, a woman's desk typically has more germ attracting things on it like lotions and/or purses. The women in the study also tended to keep snacks at their desk and food is a prime target of microorganisms.
The top spots for a man's germs: His wallet and his PDA. Neither of which are shocking as my husband (and most men) always reach for one or the other.
Interesting finding, but before you go getting all bent out of shape about being germier than your man, I do think it is important to point out that Clorox, the king of disinfectant companies, commissioned the study. The earth shattering suggestions to get rid of the germs: Use a hand sanitizer on hands and a disinfectant (like Clorox Wipes, perhaps) on surfaces -- Once-a-day should be sufficient.
There is definitely nothing wrong with killing a few more germs than you normally would but try not to get too bent out of shape about it.
