You probably need to be more specific - there are probably as many teen lifestyles as there are teens. From drug using, rave partying, early pregnancy teens to Full scholarship Intel/Westinghouse scholarship science fair winners. Explorer scouts and 4H, Jr ROTC and police auxiliaries, and so on. If you mean to focus on teen risk taking, try

If success stories are more your focus, each year 3-5 million teens complete pre-college science fair projects and 1200 compete for scholarships (even winning patents and licensing agreements) at

Student exchange program teens, legal/political interns, hospital volunteers - I don't think 15 minutes is enough time to even list the opportunities or pitfalls, let alone elaborate. Most teens incorporate a lot into their lives, and won't fit cleanly into a dozen or so 'styles'
