Trying to find out what ails the "West" so much lately, I googled:
The quick answer was:
"Autoimmune diseases are disorders that occur when the immune response acts against the healthy tissues in the body by mistake. There are more than 80 disorders that occur due to this action, as stated by MedlinePlus."
And what they called the "Full Answer" was, quite in line with the present Zeitgeist of short attention spans, not very long either:
"The immune system produces antibodies that help to attack foreign invaders, such as bacteria, viruses, toxins and other microorganisms from outside the body. However, in an autoimmune condition, the immune system cannot differentiate between healthy tissues and foreign invaders. The main cause of the condition is not known, but it has been attributed to drugs and other microorganisms. Examples of autoimmune diseases include graves' disease, type I diabetes, cardiac disease and reactive arthritis among others........."
Any similarities with Angela Merkel's "new" Germany are (im)purely coincidental, of course!
