Brain development is an overused theory. There was no such concept as adolescence as a time of extended childhood until mass schooling became all the rage. Men (fifteen and sixteen years old) were happily going to work every day, putting food on the table, building things, having meaningful friendships, getting married, raising children, and getting on just fine with their massively underdeveloped brains well into the 20th century.
This whole B.S. generation is beyond SMH. Beyond absurd. When there was still respect and common sense, a dad would say, "get your boots, son, we're going on a hike" and the kid would get his boots and say, "yes, sir" and they'd go out and have quality father and son time. Nobody was hurt, and nobody needed therapy afterward, even if it rained, because we weren't a bunch of spoiled, entitled, lazy ass wusses.
Just my opinion.
