Where is my time machine?

Is not related to softiescuties..just interesting stuff..

The New York Times reported two studies recently that found men are now happier than women. According to one of the studies, the shift has coincided with the fact that women have moved out of the homes and into the paid workforce while men have become less focused on paid work. Several studies in the 1970s found that women were happier than men.

I want to be in back in 1970s..where is the time machine?
