Okay, I'll be honest with you, I just dont get this bottled-water thing. I've never gotten it. I mean do we really need to drink soooooooooooo much water. Yes, I know it's about 75% of our body make up and so forth, but I just don't think it's natural to be constantly satiated with water... unless you're a fish.
Sidi Hakim Archuletta did a seminar in the DC area, and naturopathically speaking, drinking so much water is unnatural and in some cases dangerous. A couple of years ago, a police officer/cyclist actually died from overhydration. According to Sidi Hakim, previously, humans never took in as much water as we do now; it's become an image thing.
In addition to this -- and although I realize the concerns regarding the DC-area tap-water supply -- it may just be best to use a filter attached to the tap. I do realize that in certain parts of the world, it is better to drink the bottled water rather than the tap water even with a filter; but honestly speaking, we don't live there.
So consider careful consumption; substituting the bottle of water with foods that are high in water (specifically fruits and vegetables coz everyone needs their greens anyway!); and try kicking the water bottle habit...because it's not just about the water, it's about the bottle too...
Finally, something I came across this morning: talk about wasteful consumption, here comes Bling H20 at $55 a pop!...Funny thing is, most people during a blind taste test preferred Manhattan tap water to Bling H20...perhaps image is everything...truth be told though, that bottle looks kinda cool...Swarovski crystals and all.
So drink up if you must, but instead of a bottle, use a non-disposable cup! :)
