It is the news no long-suffering wife wanted to hear: scientists have proved that every man needs a good night out with his friends.
According to the research, male bonding is more likely to lower a man’s stress levels than a night out with his partner, or time spent with the family.
The study – bound to be wheeled out as an excuse by men across the country – found males suffer less anxiety when out in a group.
Scientists from Germany’s University of Gottingen studied groups of Barbary macaques, a type of ape which exhibits remarkably human-like social behaviour.
Levels of male stress hormone soared when male macaques were with their partner or other family members. But when they were in a group of other males, they were more much more relaxed.
The researchers even discovered stress-related illnesses only seemed to occur among females or couples.
