Mmm, thanks, one always wonders when working too much, and significant attendant stress, how things are functioning inside. Had brain, cervical spine and cardio MRI scans in April 2016 for some neck issues which showed "a structurally normal heart with no evidence of cardiomyopathy or inducible ischaemia", but that was then. My father checked out at 48 in 1965, and his brother was found dead at 35, so it's in the family. Anyway enjoy the Crimbo as well as possible. With today's cardio skills and advice I'm sure my da would have lived to a ripe old age.
