Good physical and mental health are preconditions for long life. Good health is promoted by having healthy genes, breathing fresh air, drinking pure water, eating a nourishing balanced diet, getting enough sleep, receiving the love and affection of family and friends, having interesting and well-paid employment, enjoying hobbies, games, exercise and other recreation.
