• Hi there...welcome to the Are You a Grown-up Yet? test. Contrary to popular belief, whether or not you are an "adult" or "mature person" in the sense that most people think of it is not entirely dependent on age. Therefore, this will be measuring how old you are both mentally (and probably in actuality, if you're typical) and emotionally. I'm pretty young myself, but I am frequently told that I'm more mature than most adults and I understand/appreciate the humor of Dave Barry far better than I do that of Martin Lawrence. So have fun, get offended, and try not to take it too seriously!
