Cute story of the day

At lunch today, one of my anthropologist colleagues was telling the story of her kindergarten-age daughter and her daughter's friend.  They were discussing hand washing and the children said, "You know, it is much quicker to wash your hands if you don't use soap."  It's impressive that a 5-year old could be an efficiency expert.  What is sad is that many clinicians use the same logic in hospitals when they are 45 or 55 years old.
