Angiogram sounds invasive. No way a medical peep but surely you start with less invasive tests unless there is an indication to the contrary. If they deemed a scan suitable before they ballsed it up then surely it still us.
Only logic I can see is that they are going straight to the Angiogram as due to balls up they don't want you to have a scan that turns out to be inconclusive and then you have to have an angiogram anyway. Meanwhile clock is ticking and cynically I wonder if they have targets to hit in terms of referral to diagnosis.
You wouldn't wear an MP3 while making love would you?
/Makes note for next time.
Running = fundamentally solo activity even if running with others therefore headphones appropriate in certain circumstances
Making love = not fundamentally solo activity therefore headphones inappropriate.
Mind you following from Sussex Runner logic if you hate making love then you could wear headphones to transmit this message to your partner to save an awkaward conversation! I can see this solution in the problem pages already.
