“It is impossible to maintain civilization with 12-year-olds having babies, with 15-year-olds killing each other, with 17-year-olds dying of AIDS and with 18-year-olds getting diplomas they can’t even read.”

Context: Why are there age limits? why is it illegal to marry a 12-year old? Helen of Troy was 12. Juliet and Cleopatra were still teenagers when they became famous. Most heroines of classic novels and poems were underage by today's laws. Thomas Edison married a 16-year-old. Medical studies show that the best age for a woman to have children is between 15 and 25 (lowest chances of miscarriage, of birth defects and, last but not least, of the woman dying while giving birth); while the worst age is after the mid 30s. And the younger you are, the more likely you are to cement a real friendship with your children; the older you are, the more likely that the "generational gap" will hurt your children's psychology. Therefore it is much more natural to have a child at 16 than at 40.
