My mom died this year; liver and kidneys failed, lungs filled with fluid, suffocating, maximum oxygen support in the hospital. After several days, she was too tired to go on, went with "comfort care", supposedly minimizing suffering, but it's a euphemism for torture. I stayed with her for half an hour after they took off her oxygen mask before I couldn't take it any more -- my mother gasping for breath. After about an hour I was told she'd passed away so I should go back in -- to see her frozen with her jaw locked forward, desperately trying to get a breath. I hate anyone who claims euthanasia is wrong. Why couldn't they just replace the oxygen with nitrogen?
