Measuring Stress Levels in an Unmanageable World

An insightful piece in the HBR.  Which came up in a lunch conversation today.   Many of us are managing multiple devices now.   Will the number of devices creep upwards or downwards?  Do we need device free zones?  An unmanageable world that can be best described by the language of addiction and being chained to a (virtual) desk.  Ironically the article also mentions an App that claims to be able to detect your current stress level via heart rate variability.  If successful, this will be another example of why the devices may well prevail.
