Q. If the body appears to be mature you can figure the brain is pretty well completed, right?
A. The brain matures more slowly than the body. Maturation of the prefrontal lobes of the human brain may not be completed until the individual’s mid-twenties (long after his/her body may appear to be fairly mature). This can help to explain why some of the decisions individuals made prior to their mid-twenties may be problematic for them over time, and may not work very well for them once their pre-frontal lobes have matured.
