The "Perfect" Stranger: Your Spouse by Amanda MacMillan (from Prevention magazine, September 2007) If you want to rekindle your passion before dinner, treat your spouse as if you just met, suggests a University of British Columbia study. When researches asked 31 couples to chat up either their romantic partner or someone they just met, both sexes made more of an effort to be pleasant and likeable to the strangers. Couples were also asked to talk as if they'd never met, and their sense of well-being rose significantly. "We often take familiar people for granted and act blase or bored with them," says study author Elizabeth Dunn, PhD. "But because we want new people to like us, we tend to put our best face forward--and by acting cheery we naturally end up feeling good."
