I live in Austria where every person is an organ donor and you have to opt-out of it. Even children are donors if their parents don’t opt them out. As a result, more than 99% of Austrians are organ donors. It never occurred to me that it could be the other way around.
I know it’s irrational, but there is a tiny voice in the back of my head going “what if the ancient Egyptians were right, and you’ll need your liver or eyes or whatever in the afterlife?” even though currently right now living and breathing I couldn’t tell you what my liver does for me other than I need it to stay living.
