Hey Ralph,
It’s quite common among faith healers too. I happen to have a part-time Pentecostal preacher friend, and about 98% of his diagnosis, always ends up with the person’s pain being related to one leg being shorter than the other. The sad part is, he’s convinced that he really makes the other leg longer to correct the problem. He tries so hard, it’s difficult for the other person not to say he isn’t feeling at least a little better. Suggestion goes a long way. He used to pull this stunt all the time at the old workplace, not just at his Church. I have to admit that it was amusing as hell to watch.
