That was because it was not the hospital, but my local GP in a routine investigation about another issue.
Just to comfort anyone, it was not anywhere near Manchester because I don't live in that part of the country.
It happens as you get older, doctors seem to get more interested in you, especially if your resting pulse is low and BP is good, with a history of competing in sport followed by years of just occasional pootling about without any real efforts. It seems the effects of an athletic focussed past carry into later life, for which I'm grateful.
It keeps me on the "glass half full" side of the equation!
