Personal health describes your physical, mental, and social well-being. Your physical health describes your bodily status and what activities or habits can improve or take away from it. Your mental health describes your well-being; this ranges from your desires, your frustrations, all your thoughts, etc. Finally, your social health is how active you are socially. You build your social health by making friends, keeping in touch with friends and family, etc. All three elements of health are very important and you should make sure each one is in good condition.
