Men who complain that their wife's nagging will be the death of them may have a point.
Research has found that the burden of a demanding partner is linked to hundreds of extra male deaths each year.
Men who had constant demands and worries placed on them by their partners were two and a half times more likely to die within 10 years than those with less stressful relationships, the study of almost 10,000 people found.
The effect was so strong that it could account for thousands of deaths a year, the Danish researchers suggested. Around 315 extra deaths per 100,000 people per year could be caused by spousal demands and worries, they said.
However, women appeared immune to nagging as there was little effect on their death rates.
