druff, i think you greatly overestimate the amount of people that would be lining up to do free medical tests if they had the opportunity.
that just runs counter to everything any of this have ever experienced. for me, i'm not exactly dying to go get blood work done or get an mri, etc. these are unpleasant experiences.
in fact, most people put off testing so as not to get bad news. don't we all know old people that we have to scream at cause they refuse to find out what's wrong with them, even though cost isn't a factor for them?
