Oh, but you can order your own blood tests. I've done it before. Google "order own blood tests." I've used Health One before to run a test that I wanted done. I had insurance, but I didn't want to go through the awkwardness of convincing my doctor that it was worth doing, and I think it was only $40.
The ability to shop around is great and all, but hardly something I could reasonably expect of somebody currently suffering from kidney stones, or worse (if you can even imagine a worse state).
We here at HN know a lot about computers and programming -- even some of us for whom it isn't even our profession. We learned a lot of this stuff because it was a hobby.
Several of my real-life friends are this way when it comes to a lot of medical stuff -- despite not being in the medical profession they still know all sorts of odd things you'd expect just doctors to know just because they have been so extensively reading up on their own.
So, I guess what I'm saying is, remember the post a few months back preaching that we should 'all' learn programming? I say we should all learn more about our bodies. If and when we do, that very education will probably affect what we consume, how often we exercise, etc., ultimately improving our lives either way.
