Dr. Maryanne Fisher, a professor of psychology at St. Mary's University in Nova Scotia, spoke with us about what's going on in our bodies when we're in love.

Dr. Fisher also explains what's happening when we have that all important first kiss, and how the chemicals we produce change when we enter long-term relationships.
