"Far too many times over the next 12 to 15 years, it was brought to my attention that people who followed my exercise guidelines exactly but ignored their diet, their weight and their cigarette smoking had heart attacks at age 55"

This quote by Kenneth H. Cooper is a pointer of the importance of diet, weight, and smoking cigarettes in keeping health. Cooper's experience over the next 12 to 15 years revealed him that even if somebody followed his exercise guidelines exactly, if they overlooked their diet plan, weight, and smoking practices, they could still struggle with a cardiovascular disease at age 55. This stresses the need to pay attention to all aspects of health, not just workout, in order to maintain a healthy way of life. Cooper's quote works as an alerting to those who may be disregarding their diet, weight, and cigarette smoking habits, and motivates them to act to enhance their health.
