Yes, you have a point healing.
But, its of human nature to be optimistic. And, I think optimism is a vital part of everyday life.
Never the less, the 'this is it' remark, was a bit wrong I guess.
The point I was trying to make was, the doc 'thought' that this was a viable route to go down, and it had some reasoning to it. At this very point, its all just assumptions.
