Well, many of us regard the cardiologists as swines themselves :lol:
But no, my reference is to a scheduled angioplasty, hasn't been done yet, but the NHS is due to pay for it if the cleric comes back from holiday. It is a minimally-invasive procedure.
But anyway that is another matter. The gist of my post to mdma is that there are indeed questionable expenditures on the NHS, but teaching students via creative means is not one of these. In fact if I total up my contributions (in terms of unpaid tasks, research, lectures etc) they far outweigh the trivial expense of using a few X-ray films to teach the students techniques that can be applied to live forensic cases later. Hell, I even paid the department for a box of 100 films and I am only going to use about 70 of those, so I feel an X-ray party gonna happen with the other 30 :-D
