Some of us believe that stress science is one of the most important - perhaps the most important physical and mental health science there is - far more profound - far more capable of transforming quality of life than most realize. Hans Selye probably first applied the word stress to specific mind/body phenomena affecting all of us. The word stress came from engineering and it actually means change. So we might also think of stress science as change science as it applies to health. Thinking of it this way also leads to the insight that there is good stress and bad stress, or I prefer healthy stress and unhealthy stress. So there is a science and art to reducing the unhealthy stress (think change) in life and increasing the healthy stress (change).
