Our entire family is crazy about water. My children were literally weaned on bottled water (see reason for never drinking our tap water above) and they learned to love the pure fluid that water is. My Man purchases at least 4 to 5 gallons of water per day (not really expensive, if nobody drinks pop, very little juice, no cow milk and only coffee for a few people in the morning) and we have a gallon in the fridge, one in our bedroom and each kid has their own gallon, plus a plastic drinking bottle in their room. They also take their refillable bottle with them where ever they go. My husband and middle daughter usually have a cup of coffee or two in the morning, but they both start the day with water.
I don't drink coffee, except in very rare situations (then it's filled with soy milk and raw sugar and chocolate like a dessert) neither does my little one. We rarely have pop in the house, and no cow products. Our youngest does drink some soy milk, but that is usually with her breakfast, she drinks water also at breakfast as well as all day.
Someone mentioned that caffeinated beverages dehydrate you and it's true. You have to replace
every cup of coffee, tea, pop or energy drink you consume with yet an other 8 oz of water to stay hydrated, and those and the 8 oz to counteract them don't count towards your goal, which for most people is at least 6-10 8 oz servings of water a day.
True, our ancestors survived on little more than beer, hard cider and tea, but they lived in a time where most water was contaminated and boiling or fermenting killed the bacteria.... they also had an age expectancy of about 40 years.....
