Researchers at the University of Aberystwyth and North Carolina have reviewed studies of rates of fun in terms of sex factor, finding that men are more cheerful than women, according to the Mirror website.

Humor is a complex phenomenon with social, emotional, physiological, cognitive, cultural and evolutionary effects, according to the study authors.

The ability to produce humor is a distinctive cognitive ability, and therefore the ability to produce humor is the key factor identified in the study.

The researchers looked at several studies, including what asked the study participants to write a funny and funny comment on a cartoon image, and was evaluated by a committee that was not aware of the sex of the authors of these comments.

The study recorded a 63% superiority of men over women in terms of humor and humor.

Other factors, such as age or country, played no role in changing the outcome.

But this study does not say that any man is necessarily more playful than women.
