GROUP OF ONE HUNDRED, SENIOR CORPS] WATER, WALKING, AND FOOD Water plays a very important part in the life of man, for without it a person can live for only a short time.

Its importance is shown by experimental fasts lasting for thirty days where only water was taken, and when we consider that the body is composed of from 60 to 70 per cent, of water and that the amount which it throws off as waste has to be replaced through nutrition, we realize the value of water to life.
The average person, therefore, should take from two to four quarts of water a day.

Walking can be enjoyed by everybody, and a four-or five-mile "hike" daily makes your credit at the bank of health mount up steadily.
