Will the lie detector save our 9 year marriage?

I have just watched an Episode here in NZ 10th May 2010.
One section was about a couple called Laura and Simon - Will the lie detector save our 9 year marriage?
I would like to point out that it is obvious Laura has a condition called Grave's Disease, noted by the swelling around her neck! I would like the producers to point this out to her and get her to seek medical advice ASAP.
It can be deadly if untreated, AND give false results on Lie Detectors!!! The reason for this is the Thyroid gland has a profound effect on the heart and pulse rate of a sufferer.
Jeremy you were harsh on Linda when reading the Lie Detector results and I would advise you in future to be more selective on the people you apply such tests to!
Being a victim of this dreadful disease myself, I hope there would never be an occasion where I would need to be subjected to such a device as I know full well that none of my answers could be relied upon!
