Most people do not drink enough water. I was such a person many years ago. I just did not like the taste of it. Oh, I thought that I was drinking all the water I needed, as long as I consumed it as tea with sugar and lemon or if it came in the form of coffee. I am, however, very picky when it comes to the type of water I put into my body.
Many people live from day to day in a dehydrated state.
Without drinking water each day, we could poison ourselves to death by our own waste products and toxins resulting from the body's constant state of metabolism. Water is also essential for breathing. The lungs must be moistened by water to facilitate oxygen intake and carbon dioxide excretion. Approximately one pint of liquid is lost each day from exhaling. I could write book after book, enough to fill an entire library describing the various problems associated with not taking in enough water.
