Youthperry?

I like this thread. I like how the poll captures the 14 to 17 age range (high school students). However, I'm having trouble with the spacing of the next group that covers a wider range from 18 to 24. Traditional undergraduate college students should be around 18 to 21. Where post-graduate schooling / professional schooling / entry level job workers should be around 22 to 24 years of age. Just thought that it might be better to set the age range to be approximately equal for a better comparison.
