Is the frontal Lobe responsible for more than we know?

Anyone Under the age of 25 can't consider themselves "grown." You have not completed growing. From the womb a growth process has begun that culminates with a portion of your brain fully developing after your 25th birthday. It is this portion of your brain that holds the responsibility for your ability to properly plan, and make good conscious decisions. Most of your memories make sense at this point and you have finally developed keen impulse control.

Anyone beyond this age should not be a victim of poor inhibition. Does God require more from us now that you have a frontal lobe? Is this the age where you are no longer considered a child and now expected to make good long term decisions?

Most aged adults will tell you the majority of their mistakes in life happened before 25. Some would admit to the worst decisions of their life between 18 and 25 Others will lament their current middle aged consequences stem from pre frontal Lobe decisions.

Why then do we offer an 18 year old the ability to plan their career goal, pick a life partner or live on their own without supervision when they aren't grown? Who's culture originated with a teenager being able to move on their own, get married, join the military or have kids?

If you are under 25, learn as much as you can from those over 25, opposed to your peers that are still growing brain parts.
