If you ever happen to find yourself crossing the Capilano River in North Vancouver, Canada, you’ll have two bridges to choose from:

The first is definitely not for the faint of heart: A mere five feet wide and 450 feet long, the Capilano Canyon Suspension Bridge is constructed solely of plank and cable and sways perilously in the wind some 250 feet above the turbulent rocky tides—right out of a scene from Hitchcock’s Vertigo. Your other choice? A solidly built anchored bridge that sits a mere ten feet above sea level.

In 1974, two well-known psychologists, Arthur Aron and Donald Dutton, used these bridges as the focus of an ingenious experiment—one that sought to explore the mysterious nature of sexual attraction. It’s informally dubbed the Shaky Bridge Studywhich is why I also like to call it the Shake Up Your Sex Life study.

As our economy goes from boom to bust so too do many relationships.

Even in the best of times financial stress can take its toll on a relationship. But now, as we panic about an uncertain future, stressors become terrors, cracks become fissures, and our connections to our partners becomes all the more fraught. As we struggle to save our dollars, we allow the currency of our communication to become devalued by stress, anxiety and fear. It’s not just the state of the union we need to be worrying about, but also the state of our unions.

Wondering if he's "the one"? Forget love at first sight and focus on "love at first scent."

You know how a chance whiff of an old lover's perfume or cologne can send you right back into the agony and the ecstasy of that relationship? Even more homey smells, like your favorite childhood meal, have the ability to seemingly transport you in time, back to being that little kid again. Smell is a powerful sense that goes directly to the core of our emotional brain and it plays a key role in attraction.
