More signs of late brain maturity--stress from debt

"Researchers [at Ohio State University] found that the more credit card and college loan debt held by young adults aged 18 to 27, the higher their self-esteem and the more they felt like they were in control of their lives. The effect was strongest among those in the lowest economic class.

Only the oldest of those studied – those aged 28 to 34 – began showing signs of stress about the money they owed." Rachel Dwyer

I suspect the researchers should have included in the study the amount of alcohol and drugs these 20-somethings ingested as teen-agers. That's a known factor for destroyed brain cells, or slowing their maturity.

But then, what's Congress' excuse?
