caption: Slide 1 of 37: In a 1997 SUNY Stony Brook study, psychologist <PERSON> explored whether intimacy between two perfect strangers could be accelerated by having them ask each other the 36 personal questions below. Since Dr. <PERSON> created the quiz, he's even seen it rekindle the romance in long-term relationships. ``When you're first in a romantic relationship, there's an intense excitement, but then you grow used to each other,'' Dr. <PERSON> told Berkeley News. ``If you do something new and challenging, that reminds you of how exciting it can be with your partner, it makes your relationship better.'' These 36 questions that lead to love take about 45 minutes to complete, with each becoming increasingly personal and intense. Dr. <PERSON> and his wife <PERSON>, a psychologist who also studies love and relationships, have also used the quiz to bond with couple friends (platonically) over dinner dates.
