You can still die, just not from hunger/thirst.
And you have to hide it, or else governments around the world are gonna lock you to a blacksite and experiment on you. (I mean, you are essentially a weird mutant / supernatual being, governments be paranoid)
If I was alone, get satellite internet and set up a solar powered remote working squat in some remote desert outpost. Far from the impending water wars.
Since I have family I’ll just uh probably still drink. My kid’s a handful.
