A new study finds that "man flu," the psychological condition in which men claim to suffer more from colds than women, is a fact.

A survey conducted by a university in Cardiff, Wales shows that men feel they are suffering from flu when all they have is colds, and that they take more time off than women with the same symptoms.

Males also moan more, take more medicines and at least 82 percent of them stay in bed until they feel their condition has improved.

The survey was conducted to 2,000 people and said that 64 percent of men who thought they have flu will take a day off compared with just 45 percent of women.

According to Professor Ron Eccles of the Common Cold Center in Cardiff University, in reality, it is women who get ill more.

He said, "This is because women have more contact with children, normally the main source of infection."
