George,

Hope your recovery goes well. I hope that my looking into things leads
to something different or better but it might just work out that there
is nothing to be gained. I think with pooling of resources and ideas a
better solution might be able to be worked out.

Paul and Rob,
Thanks for the kind comments - I feel at this point I'm on the mend!
However I haven't had the Pathology reports yet.

Just finding it hard to sit for long to catch up on emails. I think I'm
missing a fair bit as I go through them when the pain 'hits-in'.

I like your thinking Rob, just knowing the 'why' for some things is
encouragement enough to keep reading. I am greatly looking forward to the
results of your research.
