[Marc-André Haldimann]

Well John,

Why answering questions at all...? That's a good question and a right one by all means. Maybe for the sake of this concept getting stranger everyday in our current world: to share?

Through sharing one can be even rewarded throughout the way the question formulated might shed some new light on informations one thinks to have gone through but turn then in a different light....bringing thus a newly won knowledge...

This happens quite frequently in my own scientific field, archaeology. It might even happen here in the forum, undoubtedly a subtle form of blessing for all passionate people who gather around TOCH. Just my two cents...
