The below quote is taken directly from a 2008 Harvard Medical Study. It also talks about how environmental factors can impact the speed with which the lobes connect as well. Very interesting. Anyway, I just read the last couple of pages of this thread and I'm not sure how the whole military thing was brought into the fray. That part doesn't make allot of sense to me. My cousin is in the Navy and from what I hear, they've had some bar brawls in Perth that make this one look like a sorority slumber party. No matter what line of work you are in or how you were raised, young people are going to do stupid things every now and again. Always have and always will.
"Human and animal studies, Jensen and Urion note, have shown that the brain grows and changes continually in young people—and that it is only about 80 percent developed in adolescents. The largest part, the cortex, is divided into lobes that mature from back to front. The last section to connect is the frontal lobe, responsible for cognitive processes such as reasoning, planning, and judgment. Normally this mental merger is not completed until somewhere between ages 25 and 30."
