Middle-aged women are not as happy as middle-aged men, according to new scientific research.
A study conducted at the University of Cambridge found that, while women start life happier, by their middle years they are sadder than their male counterparts.
This sadness comes from their financial situations, family and relationships, which increases as women approach the age of 48.
According to the study of more than 47,000 men and women over the years, men's happiness increases while women's decreases as they get older.
Anke Plagnol, lead author of the study, said: "Our approach looks at the aspirations people have and how well they fulfill them.
"Satisfaction depends on how far people fulfill their aspirations."
It was found that women are happier in their younger years because they achieve many of the things on their checklists, including starting a family and getting material desires.
But divorce and subsequently rougher financial waters can lead to women being less happy, while men – who perceive themselves to still have a good family life and good finances – become "the happier of the two genders".
