WELL! Folk singing Doctor, you sound JUST like my bossy arrogant sister, (a doctor in Scotland). I've never yet been privileged to experience "the best efforts of doctors", the ones I've come across in my long life have all been like you, ie dismissive, critical and unsympathetic. How many ordinary folk have a "healthy diets that contain myriad vitamins"? Put up or shut up indeed! That is exactly the kind of utterance I'd expect from a doctor. Utter bollocks and shame on YOU!
