Just for sake of discussion, and not to hijack a question directed at someone else, who could probably answer it better...I'm just rambly today...

I think that a major problem with "a better measure" is tied into our whole screwed up healthcare and health insurance system. A better measure would be a *full* measure of an individual's overall health, as opposed to an arbitrarily defined "Here's your label" type of measure. But things are too screwed up to offer most people that level of individualized health care, you know?
