Health Uninsurance

I was just declined health insurance from a company whose parent company has been insuring us for the past 6 years.  We won’t find out why probably for a few weeks when we get a written statement from them.  Makes me wonder though, as described in the somewhat-informative-but-highly-biased movie "Sicko", if we were just declined coverage by an automated system whose job it is to decline a certain percentage of applications and claims because they know most people won’t bother contesting it.  Either way, I’m whatever the opposite of thrilled is.
