Have you experienced that your attentions is more focused in the morning than late afternoon?
Have you wondered what is the best time in the day to have a job interview?
Is it better to have an operation in the morning or in the afternoon?
These and many other questions are explored in the superb book by Daniel Pink, When-The scientific secrets of perfect timing. This book reviews the literature of chronobiology, psychology, and behavior economics and describes the effect of time of day on human behavior. For example, students do significantly better if they take math tests in the morning than late afternoon or parolees have a much higher chance of being paroled early morning or right after the judge has taken a break than before lunch or late afternoon. Read Pink’s book or watch his JCCSF presentation and use the information to change your own timing patterns to optimize your health and performance.
