Its ok matt, im starting to get used to the debates in here.

What you say is correct as well. It all correlates around the central nervous system (which is actually what I was talking about when I said that area was rittled with nerves)
I also think you would even agree that taking a spine shot would be risky regardless whether its behind the shoulder or further back.
I agree with you, nothing beats a good old shot to the lungs.
