You don't believe there is a direct coronation between age and judgement? Am I understanding that wrong?
Honest to god I think age is a red herring. Yes, I think there has to be a minimum age to consent to this activity, and yes, I think there should be a minimum age for drinking, but let's not pretend there's a direct correlation between age and judgement or age and intelligence because that's never been my experience. If you are reasonably intelligent than I assume you have the ability to learn from your mistakes and learn from either reading, what your parents have told you etc. Over and above that, I would assume you would have the capacity to learn from just being alive. But not many, if any, ever learn or absorb life's lessons at the same rate. I consider myself reasonably intelligent, I was lucky enough to survive my youth, get a university degree, start my own business, get married and have a child, but that doesn't mean an SP who chooses a particular path in live is either smarter or less intelligent than I am, it merely means she was presented with options that I wasn't. As to the brain development theory, while I haven't yet read it, I think your brain should develop until about 40 at which time, I think issues such as memory, etc. start to impede the brains ability to absorb information. FWIW, that's my take on this without reading any studies, which admittedly could alter my perception of this.
Note: After reading this study, I actually think that your brain, and your ability to learn, is somewhat like bell curve, in that it peaks at a certain point, say mid 30's, and then slowly deteriorates due to the aging process. As possibly a complete aside, the one thing I have noticed is that practically all musicians do their best work in their early to late 20's, from the Beatles, Stones, the Who, etc.
