This article made me laugh! My daughter has been exposed to sooooo much dirt in her short life! Since we live and work on a farm, she doesn't stand a chance of staying clean. She "helps" change oil, grease farm equipment, pull weeds, trap gophers, etc nearly everyday. And I would have to say she has been much healthier than other kids her age. She rarely catches a cold.
Now, if I could just convince her that touching food that is slightly slimy isn't a reason to gag herself
