And about that bracket thing, I did realize that the numbers were a bit skewered, but the reason I set them up that way is because there's a distinct personality and mindset between those age groups.
e.g.
13- younglings
14-18 teenage, pre-college
19-25 college kids
26-30 post college, work force yuppies
and then the rest, normal 10 years "adult" span

Although in retrospect I should have gave the post college yuppies a fair chance by at least giving them the early 30s. Ah well.
