Women are experts at gossiping, and they always talk about trivial things, or at least that’s which men have been always thought. However, some new research suggests that when women talk to women, whose conversations are far from frivolous, and cover many more topics (up to 40 subjects) than when men talk to other men. Women’s conversations ranged from health to their houses, from politics to fashion, from films to family, from education to relationship problems. Football is notable absent. Men tend to have a more limited range of subjects, the most popular being work, sport, jokes, cars, and women.

According to Professor Petra Boynton, a psychology at University College London, which interviewed over 1000 women, women also tend to move quickly from one subject to another in conversation, whereas men usually stick about one subject for longer periods of time.

At work, this difference can be an advantage for men, where they can put another matters aside and concentrate fully on the topic being discussed. In the other hand, it also means that they sometimes find it hard to concentrate when several things have to be discussed at the same time in a meeting.
