I consider myself something of an expert when it comes to public restrooms. First, I'm on the road all the time, so I visit many of them.
Second, I'm female. Women use public restrooms 3.7 times more than men do.
OK, I just made that up. But it's probably true.
Most public restrooms in the U.S. benefit from the same care and attention that went into HealthCare.gov. By contrast, I was in Japan recently, where many public restrooms combine a dizzying degree of complexity, cleanliness and efficiency. (Check out image below showing a toilet with several "options.")
