Here's something you might have figured out at your high school reunion or by Facebook stalking-year-old classmates.

Being one of the cool kids does not necessarily mean being cool for life.

And now, a study in the journal Child Development confirms that suspicion.

Researchers followed ethnically and racially diverse suburban and urban kids from early

adolescence to early adulthood. The kids who were deemed cool at a young age were high status

individuals with romantic relationships who broke rules and laws. But they were no longer

viewed that way by peers by the time they were in their early 20s. The pseudo-mature behavior

that seemed so admirable at a young age, lost cachet as the other kids gained actual maturity.

Meanwhile, as the young James Deans and Miley Cyrus's aged, they had to engage

in ever-riskier behavior to keep thinking of themselves as cool. By their early 20s, they were

more likely to have drug and alcohol problems, relationship issues, and criminal involvement.

Turns out, being a cool kid has a really short shelf life.
