Last point is definitely a myth.
Yes you can die if you drink an insane amount of water, but a healthy person with a healthy diet can live purely on distilled water.
As far as I am aware it’s also still a topic of debate if a healthy person could drink seawater. Not forever, but quite a while. (Have not looked into that for a while tho)
Tldr: our bodies are insanly good at keeping us alive

I think I heard that cats can survive on seawater(not well, but better than dead). For some reason they just have baller kidneys.
