We live in an unperfect world - not only are nurses and doctors sometimes wrong in their diagnoses, even so, is the high tech equipment sometimes wrong that they use. It costs more for a mere doctor's call (just to step foot in a medical office), then even if you go in for one simple problem you end getting and having to pay for a ration of tests you don't even want. Well, unless you uninsured ... then you may possibly die in that office, while waiting for help or treatment.
I detest big pharma, insurance companies, fortune 500 chemical companies and their hunger and greed for money and power ... they don't care about us; we are all merely a "number". Empathy, what's that? Compassion, what's that? Caring, what's that? Oh, yeah, that's the era-gone-by of the traditional "family" doctor!
