Rob & Will,

My earlier comment was strictly tongue in cheek.
As recently as December last I underwent heart surgery (triple bypass) and have since embarked on a fairly rigorous excercise programme to ensure I'm in better shape in future!!
Not only am I begining to benefit from my new regime already, but I'm actually starting to enjoy my visits to the gymn!!
I too now have an impressively low resting rate (although partly due to a genetic quirk which runs in the family)

C-flat.
