Relationships are tough. It would be so much easier if our hearts weren't involved. But, since they are doing this one thing can make your relationship happy.

No, it's not drinking. But, could it REALLY be this easy?  According to a new study, pretty much all you need to have a happy relationship is . . . a decent night of sleep.

Psychologists at Florida State University found that when couples sleep at least seven hours, they're much less likely to focus on the little negative things in their relationship . . . and much more likely to see the big picture.

Sleeping also helps us keep our impulses under control, so when you're well-rested you have fewer arguments. (WY Daily News)
