Doc, don't leave us please. You are one of only two people writing in this thread who is the specialist in the field, and the second person writes even less.

What I observe is following - before all this was developing in far far away land for vast majority of readers/writers of this thread, for them it was like watching war on CNN on their bedroom TVs - part of excitement, part of entertainment, part of Monday morning quarterbacking.

And last week this suddenly knocked on their doors.

Seems a lot of people are right now going thru five stages of grief. And in this and other threads one can find plenty of examples of people in each stage.

What you wrote in this thread not only provided valuable information to the audience but I'm sure motivated number of people to change their stance on this.
