Yes @Obsidiansphere - PMK is still a thing  
Although pictures of cats and flowers will also do 
@DrBlackbird My dad has just had an excellent experience of the NHS (in Glasgow ). After his pacemaker was fitted the same day that he saw the cardiologist, a rapid appointment after noticing his inaccurate Apple Watch ECG was irregular (cue dh and me performing car Tetris at the hospital as dad had driven himself there not expecting to be told he'd be admitted) a couple of months ago, he's now been seen again quickly as he noticed one hand was a different colour to the other. An ultrasound within 10 days didn't reveal anything and a CT scan the following day. Ok, they did the wrong scan 
, so he has to go back the next day (today) to get the right one, so they can establish if it's a clot (to be treated with blood thinners) or a narrowing vein. He's not concerned though so I take my lead from him 
Another friend went to a GP after watching a bowel cancer public health ad (and having ignited the bowel screening tests he'd been sent every 3 years since he'd turned 50 ie 3 times and within a month had been tested, seen by a consultant, had radiotherapy the following week and is about to start chemotherapy.
All very fast and efficient.
And Aberdeen seems to do a good job with emergency appendectomies: ds last year and a friend's ds this year - who a few weeks later needed a further five hours surgery after a stupid student accident but unexpectedly should make a full recovery 
We hear the horror stories about the NHS (and the WM Government encourages them to help soften up the public for further privatisation 
) but we don't always see how much it still achieves.
That's not to say there aren't problems: some areas (especially in England) still seem to have a problem with F2F GP appointments (our experience of telephone triage has been good) and Covid is still putting a massive strain on resources
