It's true that the conclusion has been assumed beforehand, but that misses the point. I think Met was sufficiently clear that he was not speaking authoritively and his "evidence" was purely anecdotal.
I'm not a medical professional - but I feel very strongly about this issue and want to pass it along.
Why are so many Witnesses so sick? Why do they often seem to be plagued by strange, chronic illnesses - that often appear
to have a strong psychosomatic element? MS, Chronic Fatigue Syndrome, Self Mutilation, Depression, Repressed Memories,
Anorexia, out-of-control allergies, you name it.....?
This pretty much matches my experience as well. I've never associated with a social group whose members seemed to be afflicted with as many vague symptoms and complaints as the JW's.
