You’ve seen them in movies and probably heard couples say that they fell for their partners the first time they saw them, but can it really happen?

According to Helen Fisher, a biological anthropologist and New York City-based senior research fellow at the Kinsey Institute for Research in Sex, Gender and Reproduction, it's more possible with men since they’re more visual. "They see a woman who appeals to them physically, and it will trigger the romantic love system faster. Women are custodians of the egg, so they are more careful romantically."

Meanwhile, Rachel Needle, Psy.D, a licensed psychologist and certified sex therapist at the Center for Marital and Sexual Health of South Florida says that it would be more fitting to say that "attraction or lust at first sight" is probable.

"Within the first three to five minutes of seeing and talking to someone, we often determine whether they are a potential mate or an appropriate match. However, even if you don't feel that instant attraction or lustful feeling towards someone, the more time you spend with someone the more attracted you can become as you get to know them and discover positive qualities about them and similarities between the two of you... unless, of course, something you really don't like comes to light."

Also, Arthur Aron, research professor at Stony Brook University in New York and a visiting scholar at the University of California, Berkeley, added that timing plays a very important role. "You may be more likely to fall in love quickly if you are ready."

So what do you think FNites? Is love at first sight real or not?
