Journalists wildly exaggerate how much neurology knows about brains.

but assuming that a good prefrontal cortex is helpful for good decision making,

a soldier occupying a country w/ a hostile population where he doesn't speak the language, has a desperate need for one.

If the "prefrontal cortex" myth is true, how on earth did we send 18 year olds to war in Iraq, Afghanistan, and Vietnam?

There is no job in the world that requires more rational thinking than making life or death decisions effecting civilians, all your buddies, and yourself.

but no world government has ever said that in combat they'll only have men over 25 years of age.

Never.

Not once in thousands of years of this obvious problem, has anyone noticed the problem, written about it, or tried to fix it.

(hint: it's bullshit)

but when it comes to sex,

women under 25 who decide to date a rich, famous, good-looking movie star

are immediately diagnosed with the young stupid prefrontal cortex syndrome.

Having romantic relationships

is so much harder than living in a war zone

and being sent into combat every day and trying not to kill civilians, or get killed, or let your comrades get killed...

Gotta have full brain development before you kiss a hot guy. I mean OMG
