Just an fyi...
The frontal lobe of the brain isn't fully wired until well into your 20's. That means that:
1) critical thinking isn't the strong point of a teen, so keep that in mind when you wonder why so many of them act so stupid.
2) your brain is going to wire up in direct relation to how it's being trained. For instance, world-class pianists have a much stronger wiring between their auditory and motor controls. So, Nords, getting your kid to repeatedly exercise that frontal lobe is going to pay off handsomly now and down the road.
