How much water should we drink ?

This is a very good question. Unless one is on a very controlled program then too much is not a good thing of course. From what I have read an extra quart over all other drinks, even via sips throught the day, is a general precaution and can make differences both in the long and short term. About pure water. A study was done with all the waters on the market and tap water. Ny city tap water came out on top. I spoil myself with a more expensive water, good for babies and found at health food stores. But general tap water - you can call the local water board for purity verification - is just fine, free and convenient. Secondly, "the salt of life" is no wive's tale. 1/4 teaspoon unrefined sea salt per quart/litre. You can sprinkle it on salads and eggs, etc. You can find it at health food stores in fine granulated form just like table salt. Keep a small drinking flask or bottle nearby the whole day like the savvy youth do. Watercure.Com. I'm with you, whatever.

I have heard that gatorade is also good as it helps with the electrolytes(sp) and de-hydration.
Good luck!
