Today’s teenagers have been stereotyped as adventurous and harebrained individuals.  They are generally fond of experimenting with things until they get in touch with drugs, sex, guns, alcohol among others. According to the federal Centers for Disease Control and Prevention figures, 16,000 young adults die each year from unintentional injuries and accidents.  The most common justification for teenagers’ care-free attitude is that their brains just aren’t developed enough to know better. However, recent research shows that in some cases the fact is just the opposite, the brain matures not too slowly but perhaps, too quickly.

According to a psychiatrist, an adolescent who engages in more dangerous activities have white-matter pathways that seem to be more mature than those of risk-averse youths.  White-matter is the brain’s wiring, the neutral pathways that connect the various gray-matter regions of the cerebrum that are independent of one another.  Having a mature white-matter is necessary because it allows faster brain processing speed.  Nerve impulses also travel faster in mature white-matter. Experiments also reveal that the more mature the look of the brain, the more adventurous the teenager tended to be.
Another possible explanation is that some teenagers whose brains develop more rapidly than others become uncomfortable and a little confused owing to the gap between their biological capabilities and the social norms they must follow as kids. Precocious development of these neural tracts may make some adolescents more susceptible to engage in behaviors that society considers too adult in nature for their chronological age. It is also a common notion that teens make dumb decisions because their brains are immature. In other words, having a more mature brain may actually motivate some teens to try out new and potentially harmful experiences.
For now, these theories are mere speculation, and the researchers concede that the interaction of white and gray matter is so complex that hard conclusions remain elusive. The results of the study are relatively bare and by no means conclusive. The human brain is so intricate in nature, and one has to consider the fact that there are other factors that come into play such as the environment and certain genetic predispositions that are equally complex to study.

Smoking by teenagers fell sharply and steadily between 1997 and 2003, but the latest data from a federal survey tracking smoking and other risky behaviors among young people found the proportion of teens who smoke leveled off between 2003 and 2007.

The survey did show continued declines in some groups, most notably African-American girls. But overall, the downward trend seems to have stopped.

The data released last week come from the Youth Risk Behavior Survey, a nationally representative survey that the federal government conducts of students in grades 9-12 every two years to track a variety of risk behaviors, including drug, alcohol and tobacco use.

The proportion of students who smoke soared from 27.5 percent in 1991 to 36.4 percent in 1997 but then began to fall, hitting 21.9 percent in 2003. The 2005 survey, however, showed the rate had crept up to 23 percent. Because that change was not statistically significant, officials were waiting for the 2007 figures to determine whether the downward trend had actually stalled.

The 2007 figure is slightly lower at 20 percent, but again, the figure is not statistically significant.
