In the replies to this thread, The Witch Doctor asks this:

A Scenario:

Apparently there are some sites on the web just now claiming that the world is going to end in 2012. Some teenagers are becoming agitated.

I don’t want to be around when the world ends, so I’m going to drink some poison and present to my local A and E department on Halloween 2011. If conscious I will refuse treatment but ask to be kept pain free and as comfortable as possible while I make a “dignified exit” anticipating the end of the world.

I will also carry an AD in case I become unconscious before arriving at A and E.

If conscious, I will be assumed to be competent until proven otherwise. I will pass the competency test. I do not have a mental health problem. I have just been spending too much time surfing the web.

Should the medical staff allow me to die when the time comes and if not, why not?

It’s a good question – though I’d rephrase it slightly to “if so, why; and if not, why not?” at the end.

I’m curious to know what the readership here thinks.  Since I’ve posted my reply in the old thread, I’ll keep out of it as much as possible.
