"of which you have no first hand experience"
You know this, of course. And one more person's anecdata would be so revelatory on this issue, breaking through the logjam of regurgitated partisan talking points.
Personally, I'm waiting to hear the reason for your apparent ego investment in those two systems.
See, now, I thought that jmackinn's been so very understated and reasonable, thanks for clearing that up for me.
If you're looking for general pointers, you might try the "Criticism" sections of Wikipedia articles on the NHS of England, articles on the subject by organizations like Cato, and that sort of thing.
Walking 30 min/day adds 1.3 years to your life (source: http://walking.about.com/od/healthbenefits/a/livelonger1105....). Moderate obesity takes 3 years from your life (source: http://www.sciencedaily.com/releases/2009/03/090319224823.ht...).
But obviously, none of these factors affect average national life expectancy. Only health care does.
This is why I don't argue for or against health care reform.
Of course the systems aren't perfect, but they're the best of the alternatives.
Oh, Hell, I'll throw you a bone: what happens to comparative life expectancy numbers when you correct for differing definitions of live birth in the US and the UK?
Now, carry on.
