That is utterly ridiculous. Depending on where you draw the line at "modern" medicine, ask yourself if you've seen any kids crippled by polio lately, or seen anybody in an iron lung. Ask yourself if you've ever heard of an angioplasty, or an ultrasound examination, or a CAT scan. Is it "overrated" that tearing your ACL no longer means that you're hobbled, or that a heart attack no longer means that you flat-out die, or that nobody seems to have died of the German measles lately?
It's a long logical leap from "they still can't sure cancer" to "modern medicine is overrated".
Yup, heard of them. I've also heard of nutritional ways to prevent getting in that way in the first place. An ounce of prevention is worth a pound of cure.
I haven't been in a doctor in years and have no plans to go, unless I'm injured. They only create as many problems as they cure. Most medical doctors have a completely closed mind about using any nutritional supplements--they only know about using their prescription pad.
