Medlife crisis has a great video on how doctors actually had to "redefine death". It's been a while since I watched it, so I don't remember if he uses the words "social construct," but the video thesis is close to that, iirc

One day we might figure out time travel, and go into the past to bring back everyone who’s ever died.

Somebody doesn't understand history.
