Other than our grandmothers, we all know someone who got married before she graduated high school. Chances are this girl was not what you might call normal. Maybe she got married for the attention, so she could move out of her living situation, because she was pregnant, she had some fairytale notion of true love, or maybe she just really liked "mature" guys who could grow facial hair. Whatever the reason, it does not take a psychologist to know that these young brides do not see the world the same way as the rest of us or that their young marriages may lead to problems. Still, it is always nice to have scientific data to back up your argument, especially when trying to convince your teenage daughter not to marry a motorcycle mechanic named Buck. A new study published in the journal Pediatrics found that women who get married under the age of 18 are 41% more likely to suffer from mental disorders down the road.
