Some of the things on the list are quite painful so I imagine they won’t go down well to be dropped.
I would go for things like elective consmetic surgery that has no obvious reason including no ‘bigger’ boob jobs, jobs or nose jobs or things just because they don’t like the look of them. It would be different for say cancer sufferers who have had to have a mastectomy or something though.
No IVF.
I would also restrict surgery for the seriously obese. A lot, but not all, ailments suffered because of serious weight problems can be alleviated with weight loss.
I would, perhaps controversially, make all dangerous sports enthusiasts have healthcare insurance that deals with accident to do with their chosen ‘sport’.
I should think I will find a few more later.
