Hi Peter,
Wishing you all the best and hoping that the results of the tests are either all clear
or at worse minor and correctable without surgery.
It is not a lot of fun being in hospital and though they don't serve bacon with fried
eggs in the cardiology ward for breakfast, take heart that you are in the
best possible place one can be if another event should suddenly occur.
Just be careful not to drop the nitroglycerin tablet and take out the ward.
