Boys enter puberty later than girls, so it comes to no surprise that men mature later than women. What's shocking is just how much longer it takes men to mature completely. A new study adds new meaning to the phrase "boys will be boys" after researchers found that men mature 11 years later than their female counterparts at the ripe age of Researchers looking into the differences in maturity between genders revealed that both men and women believe that males remain "immature" well into their late 30s and early 40s, according to the Daily Mail.

Running is a sport that both men and women enjoy, whether they're racing in a 5K or a marathon, or competing for a team or their country while speeding around a track. But no matter the venue, it's pretty common to see men clock faster times than women do. Given that both men and women train equally hard, why is it that men, on average, are faster runners than women? Even the world's fastest man is about a second speedier on the meter dash than the world's fastest woman: Usain Bolt did it in 9. The answer to this gender bender is multifold, but it has a lot to do with hormones and body size, doctors told Live Science. Before girls and boys hit puberty, their bodies are fairly similar.
Newcastle University scientists have discovered that as the brain re-organizes connections throughout our life, the process begins earlier in girls which may explain why they mature faster during the teenage years. As we grow older, our brains undergo a major reorganization reducing the connections in the brain. Studying people up to the age of 40, scientists led by Dr Marcus Kaiser and Ms Sol Lim at Newcastle University found that while overall connections in the brain get streamlined, long-distance connections that are crucial for integrating information are preserved. The researchers suspect this newly-discovered selective process might explain why brain function does not deteriorate -- and indeed improves -during this pruning of the network. Interestingly, they also found that these changes occurred earlier in females than in males.

All sources I've read the first page states that the fact that women mature in the sense of physical maturing earlier than man is caused by the earlier selective prunning in brain.
