Boots, I am 78 yo, have diabetes, failing kidneys and heart failure.  My health I insurance coverage is Medicare and Tricare.  I have been in an out of hospitals the last five  years at an out of pocket cost of almost zero dollars.  I am seen by my primary care physician frequently and heart and kidney specialists every three months, these also at little cost.  All my care in Hawaii and when traveling has been excellent. 
My biggest medical costs are Medicare premiums and prescription medications. Yes maybe I am " lucky", but it is a result of a lifetime of hard work and planning.  

As a scientist, I assume you are at a university, a state employee.  As such you have health insurance after retirement for life at no cost.  Any Medicare premiums will be refunded  to you quarterly.  Why do you need federal single page medical system, that may limit your choices by a huge faceless  bureaucracy.  Appreciate what you have here in Hawaii and the USA.  You can always move to Canada.
