The question is wrong!
Philosophy is a very rational subject, which pays attention to logic and deduction, and has a lot of thinking, hoping to get the essential answer or truth.
People who choose to study philosophy are good at thinking and understand the importance of time and the nature of marriage.
As far as cognitive view is concerned, people may think that falling in love is a waste of time and energy, while those who study philosophy tend to be perfectionist and critical of the other half, so they may have less time to fall in love!
