Listening to Dr Hotze and got this wonderful quote:
What does idiopathic mean? Well, I think it means that the idiot doesn't know what the pathology is. (An idiopathic disease or condition is one whose cause is not known or one that arises spontaneously)
Excellent.
So next time you are told that you don't have a thyroid problem but have idiopathic depression or fibromyalgia or CFS, remember that to cheer yourself up.
