ASH HN: How do I die like a doctor?

"How doctors choose to die"[http://www.theguardian.com/society/2012/feb/08/how-doctors-choose-die] article trended on HN recently.

One sentence from that article made me think twice: "To see how patients play a role, imagine a scenario in which someone has lost consciousness and been admitted to hospital. As is so often the case, no one has made a plan for this situation, and shocked and scared family members find themselves caught up in a maze of choices."

So how do I make a plan for such situation? I can configure a server, but I know nothing about the alleged "maze of choices" when it comes to choosing my resuscitation plan. I don't want to end up in a situation where I choke on chewing gum and die because of DNR but the opposite extremes are equally scary.
