Steve,
Your sad news has forced me out of my self-imposed, and also, medical lurkdom. As a medically qualified, sort of, person I was a Dentist I understand a bit more than you put in writing.Also I had a ministroke years back but thankfully my body has partially repaired itself.
I sincerely hope yours does the same.

Take it easy, I wish you well from Wales and that everyday is an improvement.
Isnt growing old fun???
