A recent study in Britain showed that most people don't consider themselves adults until the age of 33.  In a similar study, conducted in the 1940s, most people considered themselves adults at the age of 25.  So, as time has gone by the "official adult age" has increased by almost a decade.

This study also determined top 10 signs that you are not actually a grown-up, but instead some sort of adult/child hybrid.  We've put together a quiz, using those 10 signs, to determine what you are.  Take the quiz below!

How did you do?  Are you a grown-up, a child, or right on the border?  Post your results in the comments!
