The French newspaper Le Figaro published a collection of scientific conclusions related to everyday life, taken from the book "The Right Moment: The Science of Timing Perfect", which contains at least 700 scientific conclusions.

The book recommends not taking any important decisions in the afternoon and postponing them to the next day in the morning or evening. Two sociologists at Cornell University scanned 500 million tweets by more than 2 billion people using a computer program based on an emotional assessment of the textual content of people posting these tweets. The results were as enjoyable as they were useful. Where it was found that the tweets published in the morning are optimistic, serious and firm. As the day progresses, tweets become more defeatist, and remain so until the end of the day as they return again positive.

This finding applies to all people in different parts of the world, since this study was conducted on people from different countries of the world, regardless of age, color, or social class of the individuals involved in the study. It turns out that the positive mood is in the faces in the morning, and drops after lunchtime, and rises back at the end of the day.

According to the book, which combines the latest research in psychology, biology and neuroscience, everything in human life is about "ideal timing" and asking ourselves "when?" Before taking any important decision in life.
