The light of the moon has been an inspiration to man for ages , which goes to the light of the sun. It adds color to the imagination of the artist-writer. Then there are things that people can do , in the dazzling light of day that seem unreal. For all these reasons , those who understand the glory of the night act as if they are staying awake at night. They use the opportunity to work at night as their own. They have more IQ than others. The reason is that the brains of ordinary people are accustomed to sleep at night , their brains are also made in such a way that they need a good night's sleep. But people who are more intelligent than usual do not get stuck in the chains of this rule but take advantage of their convenient time. A subconscious desire to break the conventional rules also shows their tendency to stay up at night. In this study, people in their 20's had IQ vs. going to bed and waking up at a lower time: IQ <75 : IQ on weekdays from 11.41 pm to 8.20 am on holidays, 12.35 pm on holidays and 10.09 am on general intelligence. 90 <IQ <110) Workday night 12.10pm to 8.32am Holiday night 1.13pm to 10.14am More Intelligence ( IQ> 125) Workday night 12.29pm to 8.52am Holiday night 1.44pm From 11.08 am, those with less than IQ 75 fall asleep at 11:30 am. Again, those who have more than 125 IQ go to sleep after 12:30. This is not a coincidence at all. It's time to dump her and move on. Not only that , they can do things that not everyone can do. They tend to be more generous people who wake up at night to experience something that broadens their outlook on life. They judge many things by their own experience , not just by rules. As a result, they become more generous than others. They are very active. It is true that a lot of work can be done when you wake up in the morning , but if you stay awake at night, you can do a lot more easily. When there is no hassle , no one comes to bother in the middle of work. So the work is smooth.
