This is a weekly series on the latest happiness research. Learn and be merry! 

Breadwinners win some, lose some – A MONEY survey of over 1,000 married adults found that when women make the same or more as men, couples are more in love, happier, and had significantly happier husbands. They speculated that these arrangements are more egalitarian. But overall, women who earn more than their husbands are less likely to say they’re very in love and they worry more about finances.

Avoid the haters – According to a study out of the University of Colorado-Boulder, obesity has a big effect on happiness only when you live in an area where it’s uncommon. If obesity is the norm – and, presumably, you aren’t being judged for your weight – it doesn’t make you much unhappier. Overall, the judgment of others has a greater unhappiness effect on women than on men.

Faster food! – A study from the University of Toronto found that living in an area with lots of fast-food restaurants makes you more impatient and less able to savor pleasurable experiences, like a beautiful hike. And even making people think of fast food in the lab – by showing them a photo – causes them to make impatient decisions, like hurrying through a task, desiring time-saving tools more, and saving less for the future.
