Water covers about 70% of the rock we live on. Since we live in a closed system its the same water from billions of years ago. Your father drank it, your caveman ancestors drank it and now you drink it, all the same stuff. Weird.
It makes up 70% of our adult bodies. 80% of an infants weight.
Its pretty cheap in some places , free in others, and in Mexico you Don't drink it.
They think they found it on mars and on one of Jupiter's moons.
and your overlooking it. Do you carry a water bottle? Do you buy a new one all the time? well stop, your wasting money. Its water, its considered a basic human right in most of the world to have access to clean water. The tap is tested a lot, only people who follow Erin Brockavich can die from the municipal water supply (science.) I read something a while back which made sense, if everyone is pumping more money into bottled water, less funds for municipal water supply. Less funds means no new projects, which means i don't get to drink fresh desalinized water. I WANT SALT FREE SEA WATER. Aquafina even got caught a while back taking water from the municipal water supply and then bottling it, shame. Raise a toast to health with WATER (yes from the tap.)
So ask yourself, 8 cups a day is bull-o-knee , are you drinking enough? Start carrying a water bottle with you everyday and push for a gallon. Hyper-hydration can happen but not to you because you know how much water you drink (a gallon). So get to it?
Moral: Drink more water its good for you, stop buying that bottled crap.
"I don't always drink water, but when I do I stop having common health problems."
