The common definition of health is the ability of a person to remain free of illness and injuries. But health is not only about disease. It is something more than that. Apart from disease, we need to think of other factors such as safe drinking water, clean surroundings etc. because they affect our health in various ways. If people fail to get these basic amenities of life, they will fall ill. Being active and in good spirits are also essential part of health. We also need to be without mental stress, because we cannot be healthy for a long time if we are under mental strain.
