Different happiness levels between men and women

There are some comparison studies about different happiness levels between men and women. These studies show some differences but, are there conclusive?

For example, men spend more time relaxing than women. Despite this, another study revealed that women rated their happiness higher than men.

In fact, the results of the happiness survey at Burbeslook University show that women are generally satisfied with most aspects of their  life. According to this survey, five women out of fifteen consider themselves very happy with her life against two men. Besides three men in opposite of one women had below average in his happiness levels. Only in middle average, men was more happier than women.

Are these results enough in order to extract reliable conclusions? Probably not.

In my own opinion, happiness is about the person not gender. I think that to be more or less happier depends of your personal view of life not if you are a man or woman.
