Young people must adopt a lifestyle where alcohol if used is not abused. Stress, often precipitated by alcohol excess and leading to further alcohol abuse, gives rise to unease, low productivity, increased risk taking, accidents, high sickness absence, addictive behaviour and mental health effects. This book outlines the way to be healthy and to avoid unnecessary illness. There is a beginning which should arouse curiosity at least, a middle when interest will be generated and hopefully, a happy ending when each will feel in charge and realize that relatively small lifestyle changes can cause big improvements in both mental and physical health. Alcohol excess, one of the biggest threats to society, must be replaced by a different culture. Change can be viewed as a challenge which should create a heightened sense of personal responsibility and perhaps be the catalyst for increased originality and productivity.
