In news that will cause an equal amount of lament for long suffering wives as it will joy for their husbands, scientists have proved that men need a good night out with their friends. 

According to the new research, male bonding is more likely to reduce stress levels than a night out with a partner or time spent with family members. The study found that overall, males suffer less anxiety when out in a group. 

Scientists from Germany's University of Gottingen carried out the study on Barbary macaques, a type of ape which exhibits remarkably human-like social behaviour.

The levels of male stress hormone soared when the male apes were with their partners or other family members but when they were with other males they were far more relaxed. 

So if you ever need a trump card to play when negotiating with your wife, here it is.
