Words to live by. And what do they mean? Being safe begins with avoiding injury. Practicing the art of conscious observation and interaction with one's surroundings is the beginning of safety. Then we delve into anticipating dangers and avoiding, or at least preparing for them before they arise.
Being kind means trying not to hurt anyone or anything while living the lives we choose to live. This is not as easy as is may at first seem. Every choice, even what to eat for dinner has consequences. At the very least, we might learn to be conscious of the impact of our decisions and choices on the people, animals and environment around us and beyond.
Being healthy not only means fitness and a good diet. It also means taking active measures to enhance our immune system and eat "medicinal" foods (ie. psyllium husk, ginger, garlic, leafy greens, etc.).
Being respectful is a bonus consideration. It includes respecting oneself as well as others. It includes respecting nature and life in every way, even when the taking of life seems necessary for one's own well being/survival.
