Brain scientists now believe that we don’t actually become “adult” until we turn 30 – or maybe even older.

According to Cambridge University Professor Peter Jones, there is no definition of “adult.”  Rather, it’s an actual process of becoming one – and takes three decades.

He confirms that legal adulthood doesn’t mean that you’re ready to take on the adult world.

And, as far as criminal accountability, Jones says the criminal system does take into account a criminal’s age; and judges are able to discern someone of legal age, versus a “hardened criminal in their 30s.”

Studies confirm that the “rational” part of the brain doesn’t develop until 25 – and it takes a few more years for a mature adult to be mentally present.
