Is beauty really in the eyes

What do men and women look for in a spouse?  How do we know if he or she is the one?  A few people fall for someone who is a friend first, but many times carnal physical attraction pushes us to meet strangers, which is the first step to something more.

I recently asked many friends what they find most attractive in a potential mate. The overwhelming response was eyes, in particular green eyes with blue a close second.  The other big physical factors my friends look for in women are their breasts, butts, curvaceousness, and hair.

But how big of a role do these factors play when shopping for a spouse? How important is personality or sensuality?
