Recently the term "health" has a wider meaning than it used to. It no longer means just the absence of illness. Today, health means the well-being of your body, your mind and your relationship with other people. In talking about this, we often use another term "quality of life". Quality of life is the degree of satisfaction a person gets from life.
Why do people think more of quality of life than just the absence of disease? One reason for this has something to do with the length and the conditions of life that people can now expect. Medical advances have made it possible for people today to live longer and healthier lives. Imagine that you were born in the year 1900. You could have expected on average to live until about the age of 47. But if you were born in the year 1999, you could expect to live to the age of 75.
