Men may be more likely to experience love at first sight.

Studies have found that people are strongly attracted to others who look like them and share similar personality traits. Research has also found that people are quick to evaluate attractiveness.

“Men fall in love faster, statistically speaking, probably because they are more visual,” explained Fisher. “But women aren’t far behind. It’s a basic drive, like thirst and hunger… Romantic love leads to bonding, mating and sending your DNA into tomorrow.”

Romantic love, when it goes right, can lead to healthy, happy long-term relationships, but that’s not always the case. Having a lustful affair with someone who lights your brain on fire could be fun, but is not guaranteed to lead to a long-term relationship for many reasons, considering it doesn’t take into account religion, culture, location, values and more.
