Glad I'm not the only one who does shit like that. Nothing like a bit of redlining to test the old ticker, though there are probably more enjoyable ways to test your cardiac capacity.
It's probably no comfort that you've made the GPs day, both that he didn't have to give you bad news and that he will have a nice little anecdote he can pull out next time he has someone in the surgery who is all unravelled over a year old report. Thanks for sharing the story, I feel a bit more normal. Is that a good thing?
