Its interesting (to me) that some of the funding for this work was provided by the Department of Defense. Is this common for the DoD to fund this type of research?
The US DoD health care systems supports approximately 10 million beneficiaries and has a budget of approximately 40 billion dollars, http://en.wikipedia.org/wiki/Military_Health_System .
So there is as much socialism in the US as in Sweden? :-)
This gave me a sense of wonder insight into how large the large countries are.
