It has nothing to do with a fascination with doctors and everything to do with a fascination with death. Death today in first world countries is so far removed from what death ought to be, that it's almost unrecognizable. Dying in a sterile white room, in a building that houses thousands of sick people, with bad food, busy nurses, and often alone, is what I'd imagine a dystopian future from a Hollywood movie like Soylent Green would look like, but instead it's what Death looks like today. There is no need for this, and if most of us were asked in advance, few would choose it as the outcome. Yet very few people have living wills created, nor plans communicated with close family for these circumstances.

You can't avoid Death, it happens to everyone. So it's bizarre why so few people plan for the only truly predictable event in their entire life.
