This is a really interesting but also such a sad thread to read. So many individual stories of sadness and loss 
I do wonder about the stats for Europe vs UK. 50+ years ago people died and it was sad, but anything over what, 60? 65? was considered ok - a good life. How much investigation really went into checking what precisely the person died of and logging it into the stats?
Now everyone in the UK at least has to die for a reason, the reason must be logged and lessons learned. Does every country have as much rigour around the reporting process? Or is there a mismatch where some countries are very thorough and others more lax, so the stats can't really be compared?
I think GP's have an incredibly hard job, often the patient doesn't tell them all the symptoms because they think some are unconnected and irrelevant. I went in with sudden onset really bad wheezing (in and out) and tightness in my chest - and was referred for chest x ray and blood tests.
I had blood tests last week and later in the same day I had a call from the GP to check I was 'ok' as my blood sugar was 2.4. He was quizzing me if i was dizzy or tired at all. Well hell yeh but the consultant told me it was a side effect of a drug i'm on so i hadn't thought to mention it. Turns out the dizzyness and fatigue might actually be a real problem in its own right.
A GP has to piece together so much, and to be honest I think a lot of things are watch and wait - if it gets worse it gets investigated, if it stays the same or gets better its ignored. Sometimes, they get it wrong. I've thought for a while now that if there was anything seriously wrong with me (back and fore to GP for over a year) I would presumably be dead or noticeably worse by now, so presumably I'm ok!
