It does not. What makes a man/woman mature is not the longivity of their life but how their personalty are mold. You can live a hundred years but don't have the proper mindset. 

Even a 10-year old girl makes herself mature given life experience and having the proper attitude of mindset of everything. Maturity comes from the mind and heart, not from the length of living. As I mentioned, you can have a lot of experience in love but still don't have the right attitude and mindset, you can never be mature.
