Some years ago I saw a guy at Burger King who looked like a thin Saddam Hussein. Is that worth anything?
Leviathan got bloody weird in places. And by "in places" I mean all of it. Fairly enthralling, but a manga series that definitely fits in the WTF thread.
And @Arx, that's largely what a living will is for. At least in some places, you can already have appropriate medical treatment (including information release, I do believe) dictated beforehand, to varying degrees. Just have the appropriate papers on you or filed somewhere accessible. Hospitals being a bit more proactive in informing patients they can write the things and the degree to which they can/will be followed in the jurisdiction in question would probably be a good idea in general, though, sure.
E: Though, at the same time, being in the states I'm a bit leery about the hospitals having much input or being allowed to put pressure on (potential) patients regarding such things. I would
entirely expect some of the rat bastards we have running hospitals (or worse, the insurance companies) to abuse that sort of program, trying to coerce the injured or ill into preemptively agreeing to excessively expensive treatments.
