What the article actually says is more like “we might be able to revive you if not too many if your cells have died, even if your heart and brain seem to have stopped.”
As long as your brain mass has not deteriorated you should still have access to at least your long term memory. But in theory it could range from a terrible hangover to amnesia and brain damage, and in that case recovery may take longer and you may end up being a completely different person, as it can already happen with some accidents.
My death is when I permanently stop experiencing life.
Not sure what that means for an 'Upload' scenario... I guess he's just a swamp man of me and he's alive but I'm not anymore... but I'm not signing up for the digital afterlife anyway.
And this is why I carry an organ donor card prohibiting taking my organs.
Death is a poorly-understood process and I don't want doctors under extreme time pressure to decide when to end it.
