Everyone thinks that you are supposed to go to the hospital when you are dying

Do they? I often hear of people wanting to die at home if they have the choice, there is also hospice care. Hospital would only make sense if you have something that might be possible to treat, at least at the point of deciding to go.

Glad to have the NHS though, so there is no cost to worry about. Pretty sure you can get cremated for under £1k, you don't need to get a gold plated box.
