"The 4th H is Health." Your 4-H pledge says, "I pledge my Health to better living." This means that you must develop good health habits. Because your health is effected by your habits, this unit of the 4-H health activity is devoted to the study of personal health habits. You are expected to study your habits, determine ways for improvement and to correct some of your faults. Usually, it is advisable to try to change only a few faults at a time; rather than all of them at once. If you continuously work at self improvement, you will be surprised at how fast your health habits improve.
