A friend of a friend's mother died recently, lung disease, passed out while smoking and they noticed because she had dropped the cigarette and set herself on fire, she died in hospital while breathing 100% oxygen, or so my friend says, I'm not sure they actually give patients such a dangerous (to them and everyone in the room) amount.
We remarked how cruel it is to try and keep someone in such a condition alive, that rather than prolonging her suffering with oxygen they could have ended it swiftly and painlessly with nitrogen. I'm worried my own mother will die in such circumstances, I'm worried that I'll have a stroke or something and be unable to either live or kill myself.
I reckon someone could make a business out of this, a hitman agency where people go to take out contracts on themselves.
There's an agency and a bank, you purchase a contract with the agency which the bank holds in trust, you make regular payments to the bank to keep the contract closed, the interest on the amount paid for the contract goes to the agency. The bank wants to keep you alive so you keep making payments, when you stop making payments they have no incentive to keep the contract closed. The agency gets to keep whatever amount of the contract remains after they've paid the hitman who killed you, if you die of natural causes before the hitman can kill you the bank gives the money to an elected charity or relative.
This gives the hitman an incentive to be not-too-subtle in killing you and the agency will prefer hiring hit men who kill their targets decisively as this is after all the service their clients are paying for. Legally I imagine it would be a lot like marijuana in Australia, technically illegal but not something the police actively pursue you for or most people in the public have a problem with.
Just imagine some guy in leathers and a motorcycle helmet rolls up on a hospital, walks past the line up to the front desk and states a name, the nurse doesn't look up just stares at her screen and states a room floor and bed number as if talking to herself. Indeed everyone in the room is pretending he doesn't exist as he proceeds to the ICU, respectfully giving way to doctors and nurses attending to a moving stretcher, when he gets there he finds the bed, checks the clipboard, comes up alongside while pulling a small silenced pistol out of his jacket. Turns off the heart monitor, presses the barrel to the patient's chest and puts a single bullet in their heart. After checking their pulse he puts the gun away then turns around and walks out, being ignored by everyone as he goes, giving a quick nod to the receptionist before he leaves.
