It is most difficult for owl men to be faithful to their partner, psychologists from Duke University (USA) are sure.
The more shifted to the night the cycle of wakefulness in a man, the more numerous his sexual partners, the less inclined he is to fidelity and the earlier he starts a love life. Such intimate information is shared by psychologists and anthropologists from Duke University (USA) and Goldsmiths College (UK), while reminding that the daily «schedule» of sleep and wakefulness depends mainly on the work of the «biological clock» of our brain*. Perhaps it’s just easier for “owls” to show their talent for a seducer in a nightclub or at a late party? However, the authors of the study think that such a man is more interested in women who know … that he is unlikely to fall asleep when he gets to bed.
