Actually I have no idea where I heard this it was many years ago, 15+. I think it might have been used as a form of torture/execution, where they used a clamp that applied pressure to the temple (totally pulling that out of my ass).. ya gotta remember the temporal arteries are in the... temples, and any constriction of a artery causes some ill effect in one way or another. There is also some illness that causes the temporal arteries to become inflamed which I would assume causes some loss of blood flow, symptoms include vertigo and fatigue, all this coming from someone who's extent of medical knowledge come from watching ER and House :thumbsup:
