Why Guys Can't Grow Up

Is the Problem Cultural or Chemical? What's Happening to Boys? Are we surprised at the fact that boys are neglecting personal responsibility when their chief 'hobbies' are countless hours killing computer generated aliens/police/prostitutes/gangsters/Islam armies, and watching Spike TV? How much have we encouraged maturity in guys when we tell them that their natural penchant for laziness is really nothing more than the amoral chemicals forcing their brain and body into slothfullness? Maybe we need to try somethingnew like stricter parenting, less TV, more reading, forcing them to do their homework and corporal punishment in the school for poor behavior. But then that would require more maturity and responsibility in adults. We're sunk.
