You've probably heard the old saying that girls mature faster than boys. So when do men reach maturity? Is it in their teens, 20s, or 30s? Keep going.
According to a survey commissioned by Nickelodeon UK to promote a new show called "Wendell & Vinnie," men reach maturity at age 43 -- a full 11 years after women. The survey showed that eight out of 10 women believe that men "never stop being childish."
Women were also twice as likely as men to feel that they are the adult in their relationship.
