I read the artical forthe second time and form my own opinion.
I think happiness is not a complex thing. It does not have lots of relationships with age or something else.
Everyone has his own definition of happiness. When I was young , I thinl p;aying without stop is happiness. When I was a student , I think getting a high score in the test is hapiness. In different periods, I have different definitions of happiness. So I think happiness does not related to age. Maybe girls have other definitions of happiness. But no matter how reasons changing, the result is happiness. So I think we need not to think about which kind ofpeople would be happier.
I don't agree to the quotation of "there is no fool who is happy, and no wise man who is not." I this an intelligent person will have more troubles because he has to think about lots of things. But fools won't.
