Nurse here: This drives me nuts. Patients tell me all the time their harrowing story about how they were "dead for 6 minutes" or however long, before being "brought back to life" and their oxygen depleted brain made them hallucinate heaven, and how real it was. Dead means brain death. Your heart rhythm at the time has nothing to do with it. Unfortunately, explaining this to someone who is trying to explain why they appreciate life now makes you an asshole, so I don't.
Assuming this is real: Some people are incorrectly declared dead and it becomes a gigantic bureacratic hassle to deal with. I could see those poor bastards needing to get a copy of the certificate for themselves to try to clear it up.
Because in this Boring Dystopia, "computer says dead" is going to make it impossible to do almost anything. However, for some brave adventureres, I suppose it could be a brand new start.
Pretty sure someone just typed in “Myself “ where the name is supposed to be. And the “Someone else” box is a selection list for relation to the person like Spouse/Child
