You definitely need H2O. I'm just questioning the need to literally drink it, since you already produce high quality water in your body by burning hydrocarbons.

Yeah, but you can't make enough of it. I think it is more important what quality of water do you drink. Tap and plastic bottled water is not good. I use a professional RO system, but for years I drank distilled water (I'm lazy to do it every day).
I find it in the high quality food I already payed for anyway. Even when I don't consume anything liquid for days I thrive and have zero thirst. And most importantly, I don't have to pee all the time 😉.
