I got to see the IBM demonstration of how their tracking system works.  It can monitor the doctor to make sure he washes his hands for the minimum require amount of time before he touches a patient, the location of a patient, whether he falls, etc. It seems like a lawyer’s agenda to deal with civil law suits. The Goths in their legal system had a more direct way of dealing with the excessively litigious nature of their society.
