This is messed up. A Harvard study says your relationship will go far if you and your S/O answer these questions the same.

1) Do you like horror movies?

2) Have you ever traveled around another country alone?

3) Would you pack up your bags and go live on a sailboat?

Although they don't say why, sharing the same three answers could mean the two of you are perfect for each other. 

Meanwhile, men should also specifically ask a fourth question: whether or not his potential love likes the taste of beer. Experts say that if she says yes, she is 30 percent more likely to sleep with him on the first date than women who say no.
