1. People tend to fall in love with other people who are like them. Shared values, life experiences, levels of attractiveness, and age all can make a major difference.

2. If you want someone to fall in love with you, it might help to resemble their opposite-sex parent. That can mean hair and eye color, but also age. Children of young parents tend to seek out young partners more often.

3. There's some evidence that scent can play a role in attraction. Ovulating women, for example, may prefer the scents of men with more testosterone. And men may prefer the scents of women at certain times in their menstrual cycles.

7. If you and your crush live close to one another, it's more likely to turn into something — because you can get to know one another through running into each other. At least, that's the case for college students in their dorms.
