2. Do opposites attract?

The ability to put a positive spin on your partner’s behavior (Berscheid, University of Minnesota) 2.Length of Courtship. The longer the courtship, the longer the relationship will last (Huston, University of Texas, Austin)

9. K-I-S-S-I-N-G Kissing as part of romance is believed to be older than recorded history. One theory states that kissing started as a way for mothers to pass on nourishment to their infant children. Women use kissing as a method to measure partner’s health (Hughes, Harrison, Gallup, 2007) Kissing also appears to activate neurons that promote empathy and reduce inhibitions (Ramachandran)
